Giving something away shouldn't require something in return.
I seriously doubt $30 is going to break anyone's bank.
If I give something away to someone who doesn't seem grateful for it (or, at the very least, for the gesture), I might not choose that person the next time I donate, but it wouldn't put me off of donating all together.
If $30.00 doesn't "break your bank" ... then consider yourself among the lucky ones.
Donations are made to benefit ones who are in a situation where $30.00 is the bank ... period. And I do that when I have the means.
Gifting my stuff to someone who's just looking for another hobby ... THAT is not a "donation". It's a gift, and a gift ABSOLUTELY requires something in return. At the very least, a "thank you" or, in the case of a site like this, pictures of the gift and/or the results.
I don't feel that a "gift" is just another way of throwing away my old junk.
Okay ... sorry to hijack your thread, Steve. I'm stepping down off my soapbox. No more from me on this subject.
