If all your games are complete, yes, you can do that without penalty, except for an ugly withdrawal stat, that does not seem to affect anything.
How to leave a tournament

Well, if you have played all your games-what is the point in leaving. If you withdraw-you get (quote:"an ugly") statistic that tells everyone you withdrew when they look at your tournament stats!
If you have not completed your games-you still get that "ugly" stat beside your member name..
However, if the tournament has not started-you can withdraw.
So the choice is yours. (I recommend only entering tournaments you want to complete) and see through).

Oh, I thought this meant how to make your exit at an OTB tournament. For that I'd have to say horseback is your best option.

Any ongoing games will be resigned.
I have signed up for 10 tournaments, in some of them i actually got first and will move to a second round, but in majority of the tournaments i didn't qualify. Can I leave these tournaments so i can join new ones?
