Hi Galen. It's the same for me, I don't trust charities very much. It's also the same for me, distrust is not synonymous with doing nothing.
And answering the question, I donate part of my time to a small organization I am part of as a psychologist. About six years ago a friend, a victim of workplace bullying, told me that a small group of bullying victims wanted to organize something so they could help others. So I signed up. Since then I give time, money and, when necessary, I assist victims in consultation at a symbolic price.
This is my experience and I am glad that you enjoyed this charity auction and that everything went well.
