Server 168 opened Oct 8th, Server 169 opened Nov 9th ..

It is a little over 1 month apart from this example, but whether or not it holds true for every server release .. we'll have to wait and see.

I would say get a list of people who will move over to 170 with you, and start hashing things out. Such as, what state will you be in(so nobody has to waste a port)? Who will be the Host, VHs, etc. What name do you want your alliance to be?
Many things like this, you can do to prepare, instead of sitting around doing nothing, than flying by the seat of your pants once you're already there.
