I want to go to bed, but I think I've finally got full comment functionality back, and I've restored the previous comments. I had to add them manually myself, so I'm afraid that the posting dates are all wrong. Anyway, at least your words of wisdom are preserved...
There are two morals of this story:
- BACK THE FRELLING THING UP, YOU IDIOT!
- Maybe think about switching hosts. I think part of this problem might be host-related, and anyway, I'll be running out of space before too long.
