Moderation has been enabled

The moderation function seems to be working again. I was able to get
in (indirect) contact with the developer and he was rather helpful.
I'm still not clear on what the issue was, but it seems to have been
fixed.

I've also re-enabled posting from non-members and I hope I have it set
properly to moderate all e-mail from non-members. I'll be on the
look-out for any spam over the next couple of days if I need to lock
that down again. This is very helpful for people cross-posting with
the linux-omap mailing list, for example.

This feature didn't work correctly, so I've disabled it. Two spam
messages got through. Hopefully we are done with that!
