The other day I posted in this section and received +20 reptuation. Today, I logged in and noticed I had received -2 for the answer I provided. My question is, how do you receive negative points? I had 2 "thumbs up", now I have one. Does this mean if the OP, or whoever, decided they really didn't favor my response and took it back, but it only took away 2 reputation and left me with 8 because of their original "thumbs up"?
Also, not sure if this is the right area to be asking this question...
