Yeah, that is a bit of a problem. Me, I don't really care about that, I send out 30 cracks, I get 3 replies. Doesn't bother me really, but I can understand it gets on ya nerves
Please don't get discouraged, some of them probably didn't know they were supposed to thank you. Next time, just add a line like "if you're happy with it, please send me a short thank you, I really appreciate the feedback". Otherwise most will forget about it. So please, pretty please with sugar on top, don't stop because of this
