I had a reputation of 17 this morning, and now have 15 tonight.

Now by all means I don't mind what people rate me or if they want to change there opinion as thats what the system is for.

However upon noticing that it had changed I reviewed my reputations to see who had changed there response.  Yet no one has.  Nothings updated and I haven't got any negative or netrual reputations to bring it this low.  I don't seem to be able to find an option to repeal repuations completly either. 

Is there some sort of bug, or has someone with a low post count dropped down below the min. posting limit for a rep and it automatically been removed.

(Please don't take this as a begging for extra reputation points.  As thats not what I mean for)
