Yeah, we only let people with accounts create new ones, to
avoid spam. If you tell me what username you'd like I'll
create an account for you.

We need to actually confirm that there's a problem before
we put this in master, because if there aren't guests
that complain then we don't need to have the userfacing
switch which avoids using high memory.

Can you test this reasonably soon, please? Otherwise
I'll have to drop it from target-arm again.
