I really like this plugin, but I would like some assistance on how to setup a donation concept, rather than a product purchasing concept.
My site will have a premium WordPress plugin as an incentive for people to donate to the development of the plugin. I want to set up the plugin in the way that a user will click donate, then it will go through PayPal, and once the donation process is complete, the donor to the plugin development project will receive their premium plugin (a.k.a. the incentive) as a thank you for their donation, through my site.
I would also like to know how to set up a PayPal IPN, so that people who donated will receive their download link automatically.
