Not sure of the total criteria but maybe I can get help.
The purpose would be to bring.fighters to the UG.
The fans would donate to a paypal or kickstarter.
Then the total money would be given away to the winning fighter.
The hard part is the criteria or how to determine who wins.
Just a way to give back to fighters, especially those who have contests for fans all the time.
This was just a quick thought, so I am ready for flaming. Actually cannot wait for it :-).
