How do I set up automatic donation, not automatic billing?

[tohuvahobu]

I get the importance of automatic billing. But I don't want that. I want automatic donating, where people can set up an amount, a date each month, and a number of times they want to make the donation and be done with it.

The best way to do this is create an invoice that is reccuring called Donation and set up that client for auto billing.
