Not sure about the legal stuff, but there's something else to consider. Do you have an existing business model to base this idea on? Are people going to make donations? For what?

My suggestion - build a following first. Then think of offering advertising on your site. Also, offering your own creations. GM helpers and adventures are still popular, and a great place to establish a niche in a cottage industry.

I personally feel the donation model is a tough one. Especially in this economy. People generally want something for their cash.

Look at how online web comics people work. I think that's a good start.
