i would loke to donate to heidisql but......

I cant donate onlne because I don't want to
give out those 3 numbers on the back
of my card. with those numbers anyone can
access your checking account. don't anyone here know that?

Well you put that into a form on PayPal, not here on heidisql.com, and PayPal is well secured against man-in-the-middle attacks and other things. Also, your credit card details will not be sent to me or to anyone else. Also, you could just use PayPal without credit card.

Your reasoning is that payment gateways should accept charges against your card without the security code because providing the security code could lead to unwanted charges?
