emmett:I totally agree.  Besides, since the very first time you play a game your rating is determined as the rating of your opponent plus 400, it's very easy to misuse the resetting feature.  Look at this graph for example.  As you can see, my skill for backgammon is around 2150-2200 but my rating went up to 2528 in the beginning.  Now, if I can reset my rating, I have the opportunity of getting to 2500 again in no time while it'll take me quite a long time to get to that from where I am now.
