I've been keeping an eye on this modification
for awhile, and people seem to be really happy with it. Basically, it adds support for achievements and rewards, so that users who frequently post, add blog entries, etc. can earn identifiable icons (think Xbox Live achievements) and points that can then be spent in a virtual item store. You can also "award" negative points for necro posting, infractions, etc.
It seems like it could be a good fit on GameBanshee since I have access to a billion little icons from our equipment databases that could be used for some of the virtual items and awards. The biggest drawbacks I foresee are that it would require a significant time investment to set up and it might encourage pointless posts from users trying to score achievements.
Anyway, the reason I bring it up now is because I'm going to be rolling out a completely new forum design in the next few weeks and it seems like a perfect opportunity to include something like this. If we end up rolling something like this out, I also think we should expand the amount of user titles we have to coincide with it.
