Whoops, that was partially an oversight. Originally, it was intended since you could sign up for the wiki and forums independently, which resulted in a lot of spam on the wiki side of things. As a result, new users couldn't make new pages, but established users (Ones who had been registered for a bit. Marking them as such was automatic) could.
I've added you to the proper group for it, as well as allowed new users to create pages. If that ends up increasing spam then I'll revert that change, but we should be good.
