Just a few clarifications, for those I haven't spoken with in IRC and through e-mail already:
The servers for the German dimension will be located in the US, at the same place as the two current dimensions, not in Europe.
The dimension will be aimed at, but not limited to, German speaking players. Anybody will be able to log in on the dimension, as long as they have an open Anarchy Online account.
German players will not be forced to play on the German dimension. They are free to choose any dimension among the three.
There are no plans on allowing character transfers to the German dimension. That will have to wait for when we implement dimension travel for all dimensions.
If you have any other questions, post them here, and I'll see what I can dig up.
