PM one of the admins. IF they have the paypal account set up as a business account, you dont even need one. You can just pay them with a credit card and not setup paypal. My wife does it with her business account.
Well I actually do have a paypal account but I guess it was with an old credit card and I dont remember the password and can only go in and reset the password if I can tell them the old card number and I dont know it
