Somehow* I think people need chat script with AJAX and ability to post HTML links, bold/italic text and to kick dead/abusive users w/o page reload using JS macroses.
* I just spent 2 days trying to find any AJAX based chat. Amazing fact is I've found only one working bug-free script amongst Google's search results on "ajax chat" query.
And one I've found is most simple chat script I ever saw (messages in plain text file, 1 channel, no wysiwyg candies at all etc.). It's ok to use but still not too yammy (+ can't remade it due to lack of JS programming skill).
Thank you for your time!
P.S. Since AJAX forum is most popular here - prolly it could be a good idea to move it on top of other forums (now it's at bottom of all others semi-active forums).
