I was planning on just playing it safe but I thought I would ask for mod confirmation. I'm starting up a quest that is being run in a modified version of D&D 3.5. The base system is mostly open source but not all of it. WotC does prosecute companies for publishing third party material that includes copyright material. However, they do not make a habit of taking action against fanworks. I know a site that includes pretty much everything ever publish that has been active since 2008. Can I get a mod ruling on how much I can reveal?
