2.1 Alpha released to the normal server today. Lots of fixes and updates, definitely a lot more stable! Still will need to work on the grouping thing, but what you guys mentioned above works. If you cant get everyone in... keep trying (even if it says that it is full in the list). If it keeps saying it is full then you join a new one, and they can bail and try to join yours.

Yea its a pain, but eventually you will find a server with enough slots.
