How do you give rep?

[*SHRacerX*]

I have to admit it....I thought it was kind of hilarious when some troll would get on the Bengals message board and EVERYONE would negative rep the hell out of him and he would have something like 5 posts and -50 rep. They would disappear and come back with a new name and the same thing would happen.

Kind of funny, I didn't even know what "rep" was on the teams board for the first few YEARS I was on it.
