I saw alittle below someone suggesting to have a forum chat and was denied because it might invite spammers.
If that were the case, and nothing else, i know a good chat system thats 100% spam free. Flashchat. I know a few forums that use it, and it is an amazing chat system. allows for file transfers, custom rooms, backgrounds, smilies next to your name
and tons of other toys.
Chats have turned out helpful on the other forums im on..
Just sticking the idea out there. If there was more to why no chat, i missed it because its 1am
