Yes, we have tried to do it in the past, but it didn't really work out. 2nd trial, hopefully it works better this way.
However, with this method, you have to 'donate' to us in order to pay us. All the methods PayPal have do not really meet our requirement, which is a simple form to fill in the amount & pay. So far, only this 'Donation' button works this way.
So, try it out, and let us know.
