To all you developers who are receiving donations via paypal:
Apparently, paypal deduces 2.9% + $0.30 per received donation. This seems rather disadvantageous when most donations are probably just a few bugs per transfer.
I heard that you can register your paypal account for "micropayments", where paypal instead deduces something like 10% + $0,10 per transfer. So it is better for small amounts but worse for greater ones. And you need to register a paypal business account for that.
