Flattr have changed their terms an conditions. Since I haven’t received a single cent via Flattr, I really can’t be bothered what exactly they have changed and whether that’s good or bad for me personally. So I have closed that account for good. That leaves only PayPal, if you want to make a donation to GExperts. Sorry, if that’s an inconvenience. And please remember that I’d prefer you to contribute to GExperts in one of the other means described on that page than money.
