Pool the money together and give it to the most helpful person, a random person or a random helpful person once a month or something. Free help is great help. But other than money, I have no way to return the help! I am fairly NOT computer literate. So, it is best I answer questions for NOone.
Or use the money for server costs or whatever. I have the first $20 to contribute. Or is there already a donate button and I am just missing it?
