i don't want this to be long, so that's why I want it here.
I'm currently debating a creationists who denies evolution becasue her refuses to accept that we have observed speciation. If you all would be so kind as to give a list of examples and perhaps websites or other refernece material I would be quite grateful

try talkorigins
Try this website for starters:
Observed Instances of Speciation
Talkorigins is usually a good starting point for things that come up in the creationist vs evolution debate.

Start here...
I started a thread here more than a year ago with just such an objective. A lot more examples have appeared in other threads since, but I think you will find quite a few here to start with.
There was also a nice example of sunflower speciation on an island mentioned here .
Kuresu, this should really be a PNT in the 'biological evolution' forum - its not 'coffee house' material. That way, you would be quickly directed to existing info on the topic.

Re: try talkorigins
that faq (section 5 of it) is really quite good. thank you. THe only way he can deny speciation now is to irrationally wipe away the evidence for it.

Not a "Coffee House" type topic - Moving to "Links and Information"
So far, it is a valid "Links and Information" type topic. But remember, the "L&I" forum topics are for links and links anotation only, and not a place to debate the content of the links. If you wish to debate content, go to an appropriate Biological Evolution topic, or propose a new topic via the Proposed New Topics forum.
By the way, the promoted version of the topic EZscience cited in the first sentence of message 3 is Macroevolution: Its all around us.... It is now closed at 306 messages (all topics are closed when they hit +/- 300 messages.

2 sites come to mind.
http://www.anwsersingenesis.com (or org?)
http://www.icr.com (or org)
Creationism (which these sites support) supports the view that speciation happens constantly (or did) because ancestors of each type of animal had a massive gene pool.
They say that all racial data
in humans (who are a single species that wont change)wa present in Adam or Noah and that changes in racial type were due to population isolation and loss of data narowing the gene pool.
Those would be the best sites to collect data.

The problem with this debate on either side is that most of the time a speciation event cannot be isolated to a specific individual or time. Say that you have a group of species A1 that somehow got isolated from the main body of its population. Through time and lots of little changes in its gene pool, we can adequately call this group A2. But when do we decide that A2 is a different species than A1? To try to answer this question is like try to pin point the exact year the Bronze Age ended and the Iron Age began.
The 'few' instances that we have observed speciation taking place (the examples that people have pointed/linked to in this thread) are simply minute changes that the typical creationist can simply dismiss due to the apparent similarities still exist between the daughter and mother populations. And in many of these cases, gene flow are likely to reoccur.
Frankly, I find this part of the EvC debate quite redundant and boring. What we have here is disagreement of what defines as a species or "kind" rather than if speciation CAN occur or not. If you don't believe me, just give these examples to your creationist friend and see what happens.
The only way you can put this argument to rest is if you can point out a horse growing a pair of wings and turn into a pegasus or a cat giving birth to a monkey because that is how creationists define as speciation.
