I take it that I can let him know he can freely use our logo and other images?I am in the beginning stages of writing a book about geocaching, and would like to include information about the OpenCaching websites. What are the policies regarding usage of logos, trademarks, screenshots, and so forth?
Given that I assume he plans to sell his book and not give it away for free, I assume the Europeans / Germans might not allow usage, but I'll at least try to reach out to them.
