I found this little Rep FAQ on another board I visit, so if anyone ever wondered how the rep system works hers a break down:
User Points Until Getting a New Subtitle:
User Nobody Likes Me (most -Rep you could ever get)
User is infamous around these parts (Negatives)
User is an unknown quantity at this point: 0
User is just really nice: 5
User has a reputation beyond repute: 100
Register Date Factor: 365. For every year you're registered, you gain one point of reputation power.
Post Count Factor: 100. For every 100 posts, you gain one point of reputation power.
Reputation Point Factor: 100. For every 100 points of reputation you gain, you gain 1 point of reputation power.
Minimum Post Count: 50. You need at least 50 posts to be able to have your given reputation count towards the point totals of others.
Minimum Reputation Count: 30. You need at least 30 points to be able to have your given reputation count towards the point totals of others.
Daily Reputation Clicks Limit: 10. You can give up to 10 different people reputation in a day.
User Reputation Spread: 5. After giving reputation to a user, you must give user reputations to 5 different users before your reputation points count for the first user
EDIT: I'm not shure some of the stuff in this FAQ applies to this board like the minimum post count or the minimum Rep count.
