UI changed.
Please do *disable* firebug when you are using it, because too many ajax connection may crash firefox. I am planning to add cache to chat module to improve performance, this is the plan:
Before insert the new chat message into database, push the message into a cache file (/dev/shm, which can hold 100 messages), when user request the lastest messages, we compare the oldest messsage's timestamp $a with user's timestamp $b, if $a<$b, directly response messages in cache, otherwise, fetch the messages from database. Any advice? 1. Improve GUI
2. Use /dev/shm to cache users list (UNIX) only, this can improve performance (I will cache latest user messages later) Please give me some feedbacks to help me improve it. Thanks
Will this fall back to alternative methods on Windows servers?

The GUI is pretty rough currently, I will continue to optimize it.
And to improve performance, table structure changed, see
