Last thing before i turn back to my other endeavors.
I don't think that you should consider any compensation to anyone for either burger or shirt donations.
simple "thanks" is sufficient-and you already have done that on multiple occasions.
donations were just there to help with the project that most people cannot do themselves
keep calm and sidehack on!
Agreed, I didn't donate to the burger fund expecting to get some preferential treatment or any of it back later, I just like seeing cool stuff happen in the community.
