Here's a small, "it would be nice" type suggestion: a "mark as read" option for the some of the announcements on the main member's page. The announcements can build up over time, leaving the opinions/QC update panels at the way bottom. I know that it only takes only a few seconds to scroll, but scrolling can be a bit bothersome right after you release a video and want to check QC's frequently.
I understand that some of the announcements are important and should stay up there, but others like "Calling all programmers" and "Check your spam filter" are one-time reads for most people. So maybe a system where the admin could set whether an announcement is hidable?
Like I said, this is a "would be nice" kind of suggestion.
