Does anyone know of a FREE chatroom script written in CGI/Perl that has an admin feature: ban users, set up blocked words, make moderators, etc. Thanks in advance.

I did a quick search on Hotscripts, and these might be of some use:

Thanks, the link to ZoneCoaster has been broken, but I found a way around it (Thank you google)
