We still have to rent the hotel space, and there are other various expenses that go with running a convention, but we have cut things down to the point where you can pay what you want!
How much do you make a year? Take the numbers in front of the comma and pay us that I guess? If you flip burgers (18k/yr), give us 18 bucks. If you are a surgeon give us like 203? It's really up to you, we trust you to do us right! Really we are happy to have you, we don't want money to get in the way of people enjoying a great event!
Yes, but that's kind of a dick move! You really can't throw us 5 bucks towards the cause? That's like what a combo at a fast food joint costs!
