Joerg, Would it be possible to set up your PayPal account for recurring payments? I found the PayPal website an intricate maze when it comes to finding any information beyond the simplest operation, but if I understand it correctly, it is not possible to send regular payments without something called a "subscription" that the "merchant" has to set up. I would like to send a small amount regularly each month automagically rather than having to remember about it. I guess if more people express a similar wish then it might be worth your while.
We were discussing this idea on #maemo the other night, actually. I think subscriptions are an excellent idea. It's something I'd like to seem implemented if elected. I'm open to ideas for subscriber benefits.
