As a master, I've played almost ever my own campaings. Now I'm trying to publish my works on a blog. Perhaps is not a great work (I'm not a pro), but I am trying to do it following some principles. The most important are:
talk less, do more, meaning that I prefer posts with less opinion and more original work, and
be open, meaning that I offer materials in open licenses AND the original editable files.
I like to listen to people that know about role-playing better than me, and this is a good place to find such people!
