OK lets see:
The rep system is based on a percentage of each perrsons reputation, the more reps you have the more you can award. This is a cue we took from the other pt, because that's where a lot of our earliest members came from, and many still do.
For every hundred reps you have, you have a rep power of 1, which means that if you have 100 reps you can add or subrtract 1 point from the number of reps they have. If you have 1,000 reps you have a rep power of 10, etc.
Reps are usually awarded for posts that are very helpful or informative. Neg reps are generally reserved to show extreme disappointment toward a post that someone has made, and few of us ever use them, except for spammers, then sometimes it's funny to see how far in the red they end up.
Thanks are generally used to show appreciation for a post that doesn't rise to the level of reaching a level of above and beyond.
The Nominations are used to nominate a post that you feel is deserving of being considerred for the best post of the month. In the past we had put together awards for the member who won the best post of the month, which were sponsored by vendors, but we haven't done so in awhile because we don't have that many vendors that are active and participate in the forum and we didn't want to keep asking the same few vendors month in and month out to sponser them.
However, it would be great to get them started up again, or at least on an occasional basis.
