So I am looking for some opinions on Hacking etiquette. I have a personal project where I am doing a Dungeon World hack of Mouse Guard. I have no intention of selling it but I would like to share it on forums like this one to get feedback and share with anyone who would like to run with my ideas. I know the World system is open source so no real worries there but the Mouse Guard world and fiction is not.
If I do not sell the work do I require permission to publish in a public forum? Is it considered fan fiction? If I remove specific Mouse Guard terms like Mouse Guard and Lockhaven am I covered?
To be clear I have no issue seeking permission to use the intellectual property I just want to know if there is any recourse if it is denied. The feedback I have gotten from friends has been good and I would like to share with a wider audience if possible.
-Thanks
