Multi-Owner

Currently we can set others to be a DM.  But to collaborate with another roll20 Pro account holder to co-create a world and run it we need a co-creator option so they can work the API/Sandbox while the game is in play.  The "Creator" can set "co-creators" or remove them, just like GM's.  And co-creators have the same security rights as the Creator except they cannot add more co-creators.  If the Creator drops from the game, then one of co-creators (last logged on?) becomes Creator so the game survives a Creator disappearing.   This will help with co-creating content, API calls, creatives, etc...  so the same world can be used by other GM's with the rights to fully run the game (API) when they are GM'ing

If I remember correctly, co-GMs have access to the API Section of a campaign... They cannot change game-settings though...

It worked for me, last time I tested it (last year), my Co-GM was able to do things with the API (Mods) such as install new Mods, configure them, call them, and restart the sandbox. 

This might help. From the wiki: Creator abilities GM abilities Player abilities As for why a creator cannot leave and the GM become creator probably has to deal with ownership of assets in the game. Example: a person who bought  Curse of Strahd should not be allowed to create and abandon endless games created with it. Note that you can always petition Roll20 to change ownership of a given game, but it does require permission from both old and new owners.
