First, sorry for the message that was displayed while I had the forum offline. I'd completely forgotten that I'd added the message that I'd previously taken the forum offline to restore the missing posts and IMs.
(Also, sorry it took longer than expected.)
Second, because of the changes that I've just made to the forum, once everyone has read all the latest posts, you'll have to click on "Mark ALL Posts As Read" on the BoardIndex to get rid of all the "New" icons on the older posts.
And finally, I'm still working on one of the scripts, so until I say otherwise, it wouldn't be a good idea to expand or collapse any categories because you're likely to receive an error that you've tried to enter the forum in an invalid manner.
