someone gave me negative Karma for this and didn't leave a name. They said "heres some Biatch" and thats it. I don't undertsand, some twisted ass people.
A lot of times, it takes me a couple of tries. I'll hit the OK button and the little box will just go blank. Try clicking on the OK button about a thousand times a second. When the box says "You cannot give karma to the same post twice.", you know you're in the money.
