Sure ya can. Go to their chat room, where they have initiation tests to get in. I would give ya an invite, but I already spent them, but one I am keeping for a friend. And it'll be atleast 1 month before I earn a new one.
I tried to get into their chatroom from this page, but even there it says I need an account to get in. When I try to sign up, I get the same message about the sign-up limit having been reached.
