This is a bid for just part of the project, an online chat-room. I will build you a PHP/mysql based chatroom that will interface with your user database (so only registered users can use it) with all kinds of admin features -- banning, silencing, voicing, etc -- and a bunch of cool user stuff like coloured text, different fonts, smilies, that sort of stuff. Contact me and let me know. If we just talk, you're under no obligation whatsoever to hire me, and you definitely won't regret it.
