As posted above, they're moving to new servers, have new forum software and the admins have a LOT to do getting everything up and running, so downloads are one of the things awaiting completion. They'll be back soon, curses notwithstanding!
This weekend marks the start of the main transfer of the CFS3 forum to the new setup, so service will be flaky until that's finished. I can't get on tonight, but I'm sure I won't have too long to wait before normal service is restored.
