Update !

The tournament committee decided that I should go unpunished. They just gave me a "yellow card" as they said and the next time it happens I get DQ.

The reason being it was the first tournament I entered and the fact that I openly admitted the fact when nobody realized it. I got several responses that it was noble of me to let them know so thats always a good response to get.

I was not going to argue with the yellow card warning, as the committee had discussed it and agreed that no further action was needed.

It's not a serious tournament though, and that maybe had something to do with it.
