Starting a new alpha always seems to be an issue = with cuties all over the world the voting gets a bit messed up. Most everyone appears to be voting for the Patrick A today so it should be there tomorrow. Seems the A is up for some folks, then the B, then back to the A all in the same day for some parts of the world.
