I think you are already in, unless I am missing something as your week presence on the site hit on Monday.
Either way Welcome to the Party.
I thought that registrations were approved every Thursday, but if not, then I'm proud to be a member of this party. So, what can I do now?
Well, you can vote when elections come up, talk to other Atlasians about Atlasian matters, and even run for office. There's an introduction thread that you've probably read already.
Oh, and welcome to Atlasia and the Party!
Hope to see you help make this place active in the future!
