There are three requirements for using material from a source other than the core rules:

1. You must own a copy of the material, and be able to bring a hardcopy to the game. Having a pdf on a computer isn’t good enough unless you print it out, because we don’t want to have laptops cluttering up the game table. Assuming that the material is in print, please purchase a copy and support the people creating the games we have so much fun playing.
2. I must own a copy of the material.
3. I must approve the use of the material you want to use. Once I’ve approved it then it will be added to the approved sources page.

Please bring a copy, preferably printed, to the game.
