@Sil I plan so, but I would like to defer it to at least one month later, to acknowledge Martin's help. I hope the method is already simple enough now (at least for credit cards).
Understand, but I did not figure out a good way to do paypal webhook.
I will just provide my personal paypal address there, and if users choose to donate with paypal, I will need to update the sponsor and backer page manually.
