I did read and greatly enjoy your book series that was based (loosely) on the City of Heroes group of characters. But I for one don't intend to use any of them. Nevertheless, just for clarity, since you mentioned it, could you give a quick list of the ones that you don't mind people using versus the ones the that are NOT yours that you can't speak for? Or is that already outlined in the books or online somewhere?
