You can donate via PayPal (to firstname.lastname@example.org) using the buttons below. If you really want to donate using another method (e.g. IBAN transfer), send me a mail. Checks don't work though, Finnish banks hate them.
You can also buy me stuff directly. See my Amazon wishlist. (It may be empty. I already have most of the stuff I need.) There's no requirement to buy them from Amazon specifically, just send me a note so I'll remove the item from the wishlist so I won't get duplicates.
