Chat room would be a great idea other than I know the chat room we use now for other than vacation reasons gets about 15-20 people chatting on it and those new or not used to it can't come close to keeping up with the conversation or usually multiple different conversations
VB 4 will certainly take some effort, but I agree it is worth it. My suggestion for an implemented chat is, no guest chat. Only registered members, and even registered members that have posted to a "Introduction" specific thread. This ensures everyone gets a warm CCC welcome, and weeds out bots. If you need any help with VB 4, or moderating a intro thread, let me know.
