There are a couple of options:

1. Use your own payment processing platform (Credit Cards, Carrier Billing, PayPal, Google Checkout etc.) to do the transactions and collect your money, then authorize access to the content you publish on ThirdPresence.

2. Use the pre-integrated Bango payment solution.

3. Publish your content is a mobile application and sell the app in the Apple AppStore, Android Market, Nokia Ovi Store etc.

For more information on option (2), please see the separate FAQ topic "Selling content using Bango/ThirdPresence".

Remember that you may not sell content that is not your own or that you do not have licenses to sell. Selling unauthorized content is illegal and may lead to prosecution.
