keithcurtis said: Expected behavior. Compendium sharing is all or nothing. You can turn it off completely, but then they will not have access to spells, equipment and the data for creating and leveling characters with charactermancer. They cannot see the contents of any module or adventure you buy, however. This is to be expected. There are exhaustive sources of this information that can be searched anywhere, not just on Roll20, and of course, anyone can purchase a physical book. The best you can do is ask players to restrain themselves if you think it important. Now it sounds like in your case, you have specifically turned compendium sharing off. This should turn off the Compendium tab within that game, but again, anyone can use the website based compendium. The compendium tab is still present even though sharing is off. If I remove the compendium from the game and reload, then no one, including me, sees it. I do have a 2nd game set up as a specific compendium, was hoping to avoid having to transmog everything, now that I've sorted macros/API commands to convert on the fly from 5e to 2e. It's the monsters for the most part that I'd prefer they not see.
