Pokemon Universe is still in development. We're not sure when it will be released, but we want to have our first public beta somewhere in the first half of 2010.
Don't ask us to let you participate in private tests because this is only done by people in the team. If we need more people for testing we will probably invite the people who are active on our forums.
The staff is working very hard to improve the game before it is released to the public. I mean, who would want to play a buggy game anyway? Pay a visit on the forums every now and then to get new updates on PU.
