I thought a donation was a gift from which you received no benefit? Unless it's definition has changed now-a-days. Its up to each developer to choose what they want to give you , if anything, in return for you donation.
(CallieJo2) Maybe it would have been wiser for you to Private Message them and ask if you could remove copyright if you gave a small donation beforehand, then you can donate without all this rubbish that you seem to have pulled up with it.
(kevcj) I don't see what it is people...you've contacted
two developers and no you assume that
no-one does work for money? It is up to the individual developer to decide whether they want to accept the money in return for giving you a branding free modification. Not all developers are script kiddies in their bedroom that are desperate for money some people already have jobs and money, and do need to sell their modifications.
Remember a donation is a gift, you are not paying for a contract so don't expect one.
There are two sides to every story just thought I'd give you a bit of the other
