Darn it. I had this nice long response and it got wiped out just as I finished it. Login was required.
I'm curious how this happened. If one isn't logged in, then clicking on the "reply" button takes you to the login page. You cannot get to the "reply" page without first being logged in. The only way I can imagine this happening is if you went to the "reply" page in one browser window, then before submitting the reply clicked on "Logout" in another browser window. Can you recall the specifics of what happened?
The subjects of credentials and knowledge have been raised in this thread recently, and I want to clarify the moderator position.
Credentials are irrelevant. If you have them it doesn't make you right, and if you don't have them it doesn't make you wrong. Here at EvC Forum you are judged on the depth and breadth of your knowledge and the quality of your arguments and reasoning.
Knowledge is very relevant, but a debate isn't won simply by saying, "You don't know much, do you." It's a significant challenge to take someone whose position is based upon insufficient knowledge and improve that knowledge, let alone change their minds, and along the way you'll find your own knowledge improving. Bear in mind the difficulty of the task.
