Hi, Paul S. If you have any questions regarding how Roll20 Marketplace Assets are licensed or the Marketplace Asset EULA , please contact <a href="mailto:team@roll20.net" rel="nofollow">team@roll20.net</a> The Roll20 Wiki contains a page for the SRD 5.0 OGL License . Again, any questions regarding this are best directly asked to the Roll20 Dev Team. If you're interested in publishing RPG content outside of the Roll20 Marketplace, here are some good places to discuss this topic: /r/rpg /r/RPGdesign/ /r/gamemasters
