I've found the forum to be totally inaccessible for the last few days. Now I see that it's back up back up. Initially I wasn't able to login, but by reading this thread I found the workaround and was able to do so.
The BEAddventure is still inaccessible, though, giving a "Forbidden: You don't have permission to access this resource" error message.
If this is the result of maintenance going wrong, then trying to do it immediately before Christmas doesn't seem like the best of ideas.
