If you want to break in to a round table, all you have to do is listen to 
them for a while, find out what they like to talk about and join in on the 
conversation.  If you try to take over the conversation from the get go, you 
will be rejected.  I've never had that problem except for the message I sent 
earlier today.  Sure, it helps if you know someone in the group, but it is 
not necessary.
