Cool, a Chat Button :)
I like the addition of the chat button. That will be pretty useful if someone is in the middle of trying to get something to work. There are a few threads here where you can see exchanges posted back and forth every few minutes. Plus there's a more polite/social feel to the chat sometimes since you can say one liners like "hello", and "how are you" which are appropriate in person, or by phone, but less appropriate in a forum post.
