rating question

My rating hasn't change at all over the last 4 games.  I have only played about 12 games so I think it should change more than most.  I know for sure that two of the last 4 games were rated as I set up the seek.  Any help out there?

I don't see any reason why that should be. Maybe report it as a bug (there is a link to report bugs at the bottom of every page). 

Maybe they were Unrated??

I started two of them and I wanted them rated...  I remember leaving it at the default of rated.  I just played another game and it showed that my rating should get a small boost upwards.  So I am not sure if it was a bug or some rule.  One of the games only lasted 3 moves???

Check the details. Two of them were unrated. The other one was only 3 moves, and games that short don't count toward ratings. I think the cut off is five moves.
