I would Like To Be able to chat live and instantly its fun

At this time there are no firm plans for a tmbgforum chatroom. This may happen in the future.

Are guests allowed in ch-rooms?

Depends on the room.

No firm plans at the moment anyway. I'm sure it will be discussed more as the forum grows.

Kids today, I dunno, what is wrong with IRC, I tell ya, back in my day we were glad for such a thing, in fact, we still use it, none of this new-fangled InterWebbery, I mean, if it was good enough for Veronica, it was good enough for me.

What's that sonny? Speak up, I can't hear you, let me adjust my ear trumpet. Crimean War? Well, yes, the troops loved a bit of tiffin, of was that during the Boer campaign? I forget now.

there can always be informal chats set up
lots of different ways :)
