I have just launched a new topsites list http://topchatsites.net/ I hope to get it highly ranked in time for the term "Top Chat Sites". It is totally free to join and all sites are ranked by traffic. I am using a basic but proven php script to run the site, keeping it basic for faster loading pages. If you have a chat website or any site related to chat rooms, add your site to my new topsites list. This is the site http://topchatsites.net/
