looks pretty nice. well done kudos to you both.
it does not filter out announcements - you may not want to, but in case you didn't notice.
also, it would be nice to have the inverse. any suggestions on how to filter out discussions that have no comments or thoughts of adding feature, I haven't looked at the code myself. In other words only display discussions that have at least one comment. seems like it would be a useful counterpart with additional link in panel. e.g.
"commented discussions. "
I know of a few forums where someone posts lots of discussions and no one comments, and some people would like to see only discussions, that have comments, since the discussions with no comments often take up the entire first page and displace the discussions where actual discussion w/ commenting is going on.
I may not provide the completed solution you might desire, but I do try to provide honest suggestions to help you solve your issue.
