Drivethrurpg.com : Play It Forward event May 4 to May 17

Along with licensors on Dungeon Masters Guild (Wizards of the Coast, Fantasy Grounds) and Storytellers Vault (White Wolf), we have agreed we can do more. For two weeks in May, we will waive our share on all sales of community-created products on those sites. As a result, all revenue earned for those titles will go directly to the creators.
