Anyone can make an online donation to become a sponsor, there is no need to register for anything. The secure online payment is achieved through Paypal, which accepts all major credit/debit cards (Visa, MasterCard, American Express, and Discover), eChecks, bank transfers, and PayPal accounts. The payment can be done more easily if you already have a Paypal account but this is not mandatory for a donation to Biochartrust.
