BTW, I know what that was, now... there's another vBulletin forum I post on where the concept of "rep" (reputation) is used to reward posters for good posts or ding them for bad posts. Basically, the way it works is this:
1. You have two values attached to your account. REP is the total number of reputation points you've earned. REP POWER is INT(REP/100), and is the amount of rep that's given to another poster when you "rep" them. (For example, if you have 3425 rep points, your rep power is 34. Rep power also increases by a point after a certain amount of time elapses: for example, one point each month.)
2. When you rep someone, your rep power is added to their rep. If you ding ("neg rep") someone, half of your rep power is removed from their rep. You are also given the option of leaving feedback when you give/take rep.
3. The reppee can see when they've been given (or had taken away) rep, with the repper's name and a link to the post for which they were repped shown in the control panel.
4. There are limits as to how frequently you can rep (or neg rep) another poster.
Obviously, mods would have the highest rep and rep power, followed by long-term or important posters... newbies have no rep and no rep power, so they have to earn rep by impressing other posters.
I've found the rep system to be OK, but there are really no restrictions as to how or why you can rep (or neg rep) someone, so it becomes a bit of a popularity system after a while... on this other forum, I see people repping each other for nothing more significant than a (somewhat) witty comment. I really don't know that I'd want to see it added here.
I've got no star power. Ah well. We can't all be special, eh? But we can dream. :*(
