I'll be upgrading the forums later today. If things go temporarily kablooey, fear not. All will return to normal. Sooner or later.

EDIT: Forum's back online. Slight hiccup, though: for some reason, a bunch of users' avatars seem to have disappeared. Meh. You can upload ‘em again if you were particularly attached to yours. I got partway through the upgrade and then became sidetracked with more pressing stuff. So now the board's completely offline until I can get back to it; should be a few days.
