Thanks for not saying "What kind of a dumbass question is that!?"
I guess what I meant was, once you've clicked on 'Forums", and the three sub-directories are displayed uncollapsed...
Why aren't they collapsed (for convenience?), and
Why don't the "Member Photos" and "Chats" directories disappear when you click on "Discussions"?
(My format does not have a carat to the right.)
