@LelaCrosby: I disagree that chess.com does not need such a site. Wikipedia is an automatic source for a lot op people and having a page there gives chess.com some reliability that it is there to stay. But I will not write it, I see that as the responsibility of the staff of chess.com.
Your IP address is something which your provider gives you when you go out on the net. It serves as a mask and can not be used over time to identify you otherwise then through the logging of the ISP. Think about this: if your IP address would have been enough to identify you, then would the use of cookies never have been so popular by the organizations who wants to track your surfing behaviour.
@Polar_Bear: Being biased by group identification is more or less the way it works with humans everywhere. We are social beings after all. There are not many people who really think for themselves. Polar bears do off course, :-). Their emphasis on correctness and neutrality is at the core of their organizational culture. That has its advantages and its drawbacks. I do not think it is particularly Wikipedia.
I know Wikipedia is heavily biased by its staff's personal feelings and exaggerated correctness.
If you aren't administrator yourself, your contributions will be deleted if they don't go in line. You have no tools to reverse this. Some administrators ban without reason.
Summary: Wikipedia is unreliable.
