I believe we can support IRC chats or something of that nature; I've seen them on other boards too. However, I'm not interested in putting one on this place. First of all, they're unmoderated, and second you can walk in as anyone (as me for example) and there's no security.
I've had this suggested more than anything else and I've said no each time. Most everyone here uses MSN and that's more secure (you know who you're talking with) and it just works for everyone, so why not use that if you want to chat with LBT fans?
