Ah, bugger. Sorry, I hadn't seen the comments there. I'm subscribed to
the page, but it looks like maybe my spam filter ate it or

I'm in the middle of cleaning up and re-targetting my patches against
1.9.7 right now anyway. I'll update the page shortly.

I've also added support for calling out to an external program at
account creation time to see if a new account should be created, based
on email/IP/account name. I've got quite a few extra scripts written
locally to help with monitoring account signups and managing the
blacklists too.

More helpful things here would include:

 * better support for network addressing for blacklisting (something
   that understands CIDR rather than just .startswith)

 * support for moderation - new account holder should need to have
   their first few edits approved by existing users

< sladen> I actually stayed in a hotel and arrived to find a post-it
          note stuck to the mini-bar saying "Paul: This fridge and
          fittings are the correct way around and do not need altering"
