This post is a simple suggestion I thought of. You're the owner of your own igloo on P3D, but... what if you were able to give co permissions to another user to able to edit your igloo? Now of course you would only give permissions to a user that you can trust, obviously. So nobody can do anything unless you enable igloo permissions for them; you can be able to also remove permissions at will. But yes, that's my idea.

good idea
