I don't think there should be a "labor fee" for a charity created by a community. If there is, it would make the ones running the charity basically employees, and even though I know that's all business as usual for the large corporations that pose as charities, it doesn't seem right for a community event.

[\quote]It is actually unusual for someone providing a service for, working for, or performing administrative tasks for charities to not receive payment for said work. 

The executive management of the American Red Cross, for example are paid quite a lot for running the charity.

I don’t think that anyone is claiming that anyone involved has paid themselves a salary out of charity funds.
