Thanks to my good friends at PayPal, I can accept in-world payments using off-world currency. It's a great option if you're short on Lindens. I also handle automatic-billing for recurring payments like parcel rent or group subscriptions.
 
A PayPal account is not required. They've made it so I can even accept those little plastic thingies off-worlders call credit cards! Another shining example of how I work tirelessly to come up with new ways for you to give me money. ;-)
