Basically, Paypal would be our #1 option as far as receiving tournament entrant pre-payments. It's extremely quick, allows us to receive payments in any currency on earth, and gives us a protected account to manage and oversee all entrants who pay ahead of time (not to mention the awesome protection Paypal provides its users). Once everything's set up and running, we'll provide everyone a template with which they can send their payments (name, smash tag, region, which events you're entering, all that good stuff).
Also as far as Paypal goes, you don't need a credit card to set up a paypal account. Myself, I opened up my first Paypal account with my Checking/debit account. As far as creating a bit of extra hassle for the attendants, this is a necessity to ensure Genesis does not turn out to be the next big CoT4. Honestly, just try to imagine 600-700 people attempting to register and pay at the door...for up to 4 different events each... this creates a slew of nightmares I don't even want to imagine, including confusion concerning how much money goes where, security & organization issues, and not to mention we would literally be spending ALL day Friday doing registration. Thanks, but no thanks. =p
ALSO, we should clarify that while Pre-Payment is mandatory, *Online* Pre-Payment is not. You will have other options available to you, although they will be slightly more convoluted and delayed. We're currently trying to establish an address or even set up a P.O. Box with which you can mail your entry fees via Money Order / Cashier's Checks. So while Paypal will definitely be your best, safest and most efficient option, it won't be your only one.
