Thanks for the kind words Chip, BassChick, and Squirt.
Your issue with running out of disk space was actually kind of interesting, kind of
broke up the boredom. For me it's fun to have those "what the hell!?!?" moments when
suddenly MySQL queries start hanging forever, PHP sessions suddenly don't work, etc.
Then I remembered, when everything goes to hell, when things are breaking mysteriously,
ccheck disk space.
I hope it didn't cause you too may problems, though. It looks like probably it was pretty
much just that people couldn't post to your bored and your old PHP authentication system
went screwy.
