[Update: The major part of the upgrade has now been completed, and I managed not to break anything as far as I can tell.]

I'll be upgrading some stuff on the site over the next day or two (or three, or six, depending on how smoothly it goes), so expect BCK to disappear briefly before returning to look pretty much exactly the same as it does now.

Exciting, no?

The Facebook and Twitter accounts will be used to post updates if I accidentally break something.
