Paul708,
I see you have a pawnstar, which means you are already allowed unlimited numbers of games. Simply go
to "your settings" and increase the number in the "Maximum number of games allowed before
preventing challenges" to a number higher than the total number of games you are currently playing.
You can set this as high as you want.
You can generally find the "your settings" entry in the upper right hand of the web site, right above the
thick red line. Click on the text and you go to a new page where you can modify personal settings.
I hope that helps!
Michael
