Apologies if this is a redundant "issue report".
Just browsing around, I tried to click on "Activity" in the black menu bar that also has "Discussions", "Inbox" and my board handle. This gave me a big bold "Permission Problem" message. If I don't have permission, I'd rather not see the menu choice -- failing that, I'd like to see it grayed out and disabled.
What I was hoping to see when I clicked on "Activity" was a depiction of activity by different participants -- showing perhaps recent posters sorted by who had posted most recently, with an alternative sort by message count (or, better, "recent" -- last 30 days -- message count)
Some kind of function like that would help compensate for the much-lamented loss of the exploded tree view.
I would actually prefer an "explodable" tree view to the old FundAlarm style, but that's a personal preference.
