Hi Bolder-dash and welcome to EvC!
Your proposal is fine except where you propose your own guidelines. EvC Forum already has a set of Forum Guidelines that are enforced by moderators, and discussion participants are not permitted to add their own. Your preference for focusing on the natural selection of sexual species is fine because that is simply delimiting the topic, but participants do not make the decisions about what constitutes valid discussion. That would be the moderator's realm.
Please edit your opening post to make this minor adjustment, then post a short note to this thread letting me know you're done and I'll take another look.

Hi all!
I told CosmicChimp that I'd keep an eye on this thread. So far so good. I do see occasional hints of frustration, but no worries as of now, though it would be nice if those given to focusing too much attention on the foibles of other participants rather than the topic would try to rein it in a bit more. Just letting y'all know I'm here.

Hi Bolder-dash,
Please let moderators handle moderation issues. If you are having problems with discussion then you should post to Report discussion problems here: No.2. Participants should keep their attention focused on the topic and not on the perceived misdeeds of other participants.
About the nature of the actual topic of discussion, I thought this was resolved back in Message 22 when you said:
Bolder-dash in Message 22 writes:
Ok, fair enough, I am willing to modify my statement to include what is the modern day accepted form of Darwinian evolution..that is that random mutations are the ingredients for change, and natural selection the filter.
Participants have mentioned a couple additional important details about how they believe evolution works. These are best explained by those who have already been talking about them, but let me briefly describe each one so it is clear what I'm referring to. First, it has been suggested that mutations are not necessary for natural selection to operate. For example, if a region experiences sudden and dramatic climate change then natural selection will immediately begin weeding out those individuals and species not sufficiently well suited to the new environment.
Second, it has also been suggested that mutations are not the only source of evolutionary change. For example, all species already have a great store of variation within their genomes, and these variations can be expressed to varying degrees within a population, ranging from not at all to fully expressed. Natural selection can perform profound changes on a population by changing the frequency and degree to which various genomic traits are expressed in the phenotype.
To everyone: While keeping in mind that no one wants to read book-length messages or even long essays, I think that some explanations have been spread out across too many posts, with the result that some explanations haven't been grasped.
Please, no replies to this message.

Re: Back to Basics
Hi Bolder-dash,
I appreciate some of the difficulties you're facing. I agree that the evolutionists, who I believe are well intentioned individually, are collectively providing a confusing picture, but on the other hand I can see where correct information is being provided that you're missing. For example, you say:
Bolder-dash writes:
You can't talk about evolution without RM, your theory doesn't exist without them!!! If it does please explain it clearly how it can.
I'm sure everyone agrees with you. You can't talk about evolution without mentioning random mutations. But you *can* talk about natural selection without mentioning mutations, and several people have attempted to explain this.
...and you get to be moderated by another evolutionist...
Don't think of me as an evolutionist moderator, but instead as a moderator who understands evolution. As moderator I'm not agreeing with the evolutionists that evolution is right and creation is wrong. I'm agreeing with them that they are correctly defining evolution, natural selection, random mutation, etc.
Whenever you receive more than one definition of something, as is happening here for the fundamental terminology of evolution, you'll always be able to find differences and apparent conflicts in those definitions. No two people will ever define the same thing the same way. This is just a fact of life. You're going to have to work through the different and differing explanations in order to build your own understanding of evolution. You might find other online resources helpful. For example, Wikipedia provides this definition of natural selection:
Wikipedia writes:
Natural selection is the process by which heritable traits that make it more likely for an organism to survive and successfully reproduce become more common in a population over successive generations. It is a key mechanism of evolution.
Notice, no mention of mutations. The first mention of mutation occurs a few paragraphs further on and says this, which includes an important point you've been making yourself where it comments about the need for understanding the origin of variation:
Wikipedia writes:
Although a complete theory of evolution also requires an account of how genetic variation arises in the first place (such as by mutation and sexual reproduction) and includes other evolutionary mechanisms (such as gene flow), natural selection is still understood as a fundamental mechanism for evolution.
I don't know if you appreciate sports analogies, but I always feel that the best referees are those you're not aware of. I feel the same way about moderation. Moderators should facilitate discussions, not intrude or impose upon them. A light hand is best, allowing thread participants to work out as many difficulties as they can on their own.

Percy, I really think it is disingenuous of you to allow this type of obfuscation to continue for so long. Seems I really touched a nerve with you evolutionists.
Seeing something severely misunderstood does tend to bring responses that resemble "touching a nerve" from those familiar with it.
You're quite free to discuss random mutations as it relates to natural selection, but if you still don't understand that natural selection would go on even if for some mysterious reason random mutations ceased occurring then discussion will still tend to center on this misunderstanding. And you have other misunderstandings, for instance this here from your Message 192:
Bolder-dash in Message 192 writes:
Evolution is any heritable change to a lineage? That would make any sexual reproduction evolution.
Yes, precisely.
For as long as you continue to misunderstand evolution the discussion will tend to center on those misunderstandings. You say this is "obfuscating" your intended topic, but understanding evolution is a prerequisite to any discussion that would make sense.

Re: Back to Basics
Hi Bolder-dash,
I think you're misinterpreting what is being said, both by myself and others. When I said, "that natural selection would go on even if for some mysterious reason random mutations ceased occurring," that didn't mean I was asking you to talk about natural selection independent of evolution. What that meant was that even if all random mutations ceased occurring, evolutionary change over time would still occur through natural selection.
I also said, "You're quite free to discuss random mutations as it relates to natural selection."
I think this is enough moderator interaction. In this thread please start discussing and stop complaining. Your perceived mistreatment is not the topic of this thread. If you're having problems with discussion then please take the issues to Report discussion problems here: No.2.
Please, no replies to this message.
Edited by Admin, : Fix thread link.

Thread Temporarily Closed
Hi everyone!
I've temporarily closed this thread so that everyone can take note of my concern about the recent lack of focus on the topic. When I reopen the thread in a couple hours (probably around 2PM Eastern Time US) I will suspend for 24 hours those making discussion of the topic more difficult.

Summation Time
Given how little this thread's topic is being discussed I'm going to enforce the 300 post cutoff, so time for summations.
Please, do not reply to anyone's messages.
Please, post only summations.
Please, post only one summation.
Please, post only on-topic. I'll be hiding off-topic posts and portions of posts.
If you post before seeing this, go back and edit your post into a summation.

A Note About Summations
A summation isn't a rebuttal that happens to be your last post. Think of summations more as what a lawyer does in his closing arguments, which are made to the jury and not to the other side. Refer to the other side in the 3rd person.
