They must have had Mac users sign onto the Test server first so that they (Disney) could monitor the impact of having Mac and PC users playing at the same time.
Now that they (Disney) have gotten comfortable, they must be making all Mac users go to the Open server.
However - you should be able to sign up for a Test account... the same way all of us did. The instructions how are on one of the "stickey'd" posts at the start of the "Test Town Territory" forum.
Hurry back ...
