Lazy registration is making progress. The only problem is figuring out
when it's being *too* lazy. Like, if it has a valid session stored in
the cookie, and you give it a form login that's not valid, it probably
shouldn't go "Well, that's okay, I'll just keep using the one that
works" and not actually complain about it. But right now, it does.

On
the plus side, it now cheerfully takes a name/email combo and creates a
registration, so new users can reply to a post (comment on a blog,
whatever) just by entering a name/email, same like they've gotten used
to on blog comments. No running off to register and then coming back to
reply, the way web forums generally require. Yay.
