Suggestion for you: would it be possible to include an actual chatroom on the site or would that just complicate things? I could see that being a problem, but for people who need a really quick/simple question answered, it would be decently good. All in all, I think the site needs very little else. It's a great site, and has been for as long as I've been here and I'm guessing longer. Cheers.
I think the reason the we try to get members to post their problems instead of asking via PM, IM or chat is that other users can see the problem they posted and the solution to the problem. Its more potential traffic from search engines.
Correct me if I'm wrong but don't IM / Chat type systems on websites put a lot of stress on the server? I read that somewhere but can't remember where. It may be wrong so if it is please tell me.
