welcome to the guild - had carpal tunnel some years ago I tend to take care - I think a wacom is a really good choice, although I'm still getting used to using mine. You may use any maps I post here for personal use without asking (I think a lot in here would say the same) - but its always nice to get a "I used your map - thanks".
If you want to post maps somewhere online you always have to ask (unless noted specifically otherwise, like in a CC note) it is also the polite thing to do, we all like praise now and then
