That would be turning Discourse (CDCK) into a sort of financial broker/distribution service. That’s not something I think Discourse would be keen on doing. It could make them responsible for thousands (or more) of financial transactions. Some along the line of PayPal would be better suited for this. Handling financial transactions on this scale would be a large and separate business endeavor for Discourse.
- Site owner creates a PayPal account;
- Site owner puts a donation link on their forum.
- Members who wish to donate click on the link, and
- PayPal takes it from there.
The only thing remaining is having the details of auto-renewal setup between Discourse and your financial institution (bank, credit/debit card, etc.).
PayPal is already set up to do these financial transactions. This would distract Discourse from its core idea of making the software even better than it already is - especially when there are “Card Declined” issues. It’s like asking Discourse to duplicate PayPal’s purpose (or any other similar money exchange site).
