Over at http://forums.gentoo.org they have a nice feature which allows a user to quickly scan all the unanswered questions. By going to http://forums.gentoo.org/search.php?..._id=unanswered you'll get the list sorted by date. It comes in handy if you're looking to offer some help and possibly answer someone's question.
BTW, this site very nicely layed out (like the extras on the front page) and well maintained. I hope it gets adopted as the official forums site. Thanks for all the work you guys have put into it.
