How is "processing credit" different from paying with an ordinary credit card? You keep giving as an example "pay pal," which is a payment method that draws from other payment methods, in other words you can "pay into it." I use a credit card to buy Lindens. When I register for Tilia, do I still have to provide picture ID and SS number? So is having, say, a VISA or an AMEX card "processing credit" in your books? I don't know how else you'd buy lindens, unless you wrote a check to Linden Lab.
