How many people love the chat system and want to expand it? It looks like it's a big hit, but I want some feedback. We can upgrade the current system for a monthly fee, or I can pay one-time for a different system that will do the same thing (and maybe some more stuff). I'm just wondering how much time to spend on this as I run the site and I can't get it because it says "Chat Full!" ... we've hit the 25 user-at-one time that have the chat window open (even if you're not chatting).
