i think it would be cool to have a chat box where people could IM everyone.. Ive seen it on many forums.. and would help clear up alot of threads asking for help when people can easily tell them through the chat box.. Or to generally just chat with people..
fair enough but can you imagine a chatbox with 500-1200 users online? Loading for each etc.
It would cause TEDIOUSNESS LOAD ISSUES on the site not to mention so much spam it would most likely shut the site down in a matter of an hour
chat works well on very small to small/medium sites but something on this scale would not be worth the trouble it would cause.
Also side to that because we use such bad software on the site I'm not even sure if there is a properly supported chat frame for phpBB as there is for VB but even for VB something this size would not work well.
