Rich is being a smart aleck. It's okay to ignore him when he's bored like this.
1. You start with 10 rep points that you get just for registering.
2. If a member has over x-number of posts, they give more points each time. I think it's something like 10,000 posts equal 2 points instead of 1, but don't quote me on that.
3. Admins and MacAllister give 10-points each time.
It's also possible that you might have received a negative rep point that would detract from the total, but I don't think that's really likely. With only 214 posts, if you were doing something that was earning you negative rep points, some mod somewhere would be keeping an eye on you to make certain that you were one of them there troublemakers.
