Fragment of a discussion from Talk:March 2011 Update
Kerry,
It's because this actually a separate site, just like the various language versions of Wikipedia are actually separate websites each running similar versions of the same software. The Wikimedia "single user login" system automatically created an account for you here since you were logged in on your home wiki, but it is a new account with a new user page has yet to be created. That's why it's a redlink. Make sense?
