Can I contribute content Ive created for traditionally published campaign settings, such as Forgotten Realms?
Yes, but only as long as there is no reference to characters, places, items, or anything else that would identify that product. If you created your own version of Elminster from the Forgotten Realms campaign setting published by Wizards of the Coast, you must at least change the character’s name and any references within the character sheet linking it to Forgotten Realms before uploading it.
