I was notified of a bug yesterday in the donation form and that was that it somehow misinterpreted the comma and the period as both a decimal and thousands indicator. So if you wanted to send me 10.00, the form just interpreted that as 1000. Same with 10,00.
Now, if something like that would have happened and my tipjar suddenly got a 1000 euro tip, I would have contacted you and refunded it. You can love this website a lot, but I am sure you don't love it that much! ;-)
So, general rule is of course to always double check things, but at least this little issue is solved now.
