Erm, yeah, I think I was!
Actually I was never expecting a situation to arise and so my existing stuff is all still residing under default copyright legislation. I guess I need to decide on things "license".
Provided it doesn't contradict any Cartographers Guild reserved rights, you can consider the Plumton map as being under Creative Commons, BY-SA-NC license (latest version). If you wish to use it commercially you should contact me via private message? If it's for private home use. Enjoy!
