I've been working on member lists and artist leaderboard rankings for theOtaku. It's been a sorely needed part of the site and it'll launch this week. 
One of my favorite features for it is that it displays links to new artists who just joined the community. So if someone submitted their very first work of fan art, they're highlighted, giving you the opportunity to give them a special welcome.
What do you think is important in a member/ranking list?
