enable simple registration+discussion

Initially, we required Anyone to have permission to create User cards, but for Wagns that generally require sign-in to create cards this led to signed-out users being able to create new User (and only User) cards, which is Not Good.

Got a 500 when clicking on Invite a Friend on Sandwagn (before i reset permissions). Guess we shouldn't show that link if the current user does not have permission to create accounts.

Setting permissions fixed that, but now i'm getting 500 when clicking on Sign Up, even though ((removed reference to sandwagn)) is createable by Anyone and Anyone can create accounts ((removed reference to sandwagn))

http://sandwagn.wagn.org/wagn/Account_Request was returning a 500 until i deleted its content, which consisted of just including +*type cards, and ((removed reference to sandwagn)) still returns 500

I think the Invite-a-Friend permissions should be right now. May want help finding that other error.

Many problems found and fixed. Closing.
