my apologies, I have made a small rule change in favor of allowing submissions to be open for Donations, the edited rule reads as:

During the Jam you may list your game as Free or open to Donations. Someone pointed out to me that so long as submitters and judges download from the submissions tab instead of the individual pages, it will always download like its free. the original intent of this rule was to keep people from feeling inclined to donate simply to be a part of the Judging process. My apologies to those who were affected by this rule.

I hope this helps!
