If 2 or more people were collaborating on a map, it would be useful if both/all members were able to update the map thread. For example; me and @Muddy are collaborating on Itza, and it would be super handy if, lets say, she is away (sleeping, eating, etc), and I was working on the map, I could update it myself instead of waiting for her because she is the thread creator. This could be done by the thread creator being able to give certain members access/permission to editing the map thread. Similar to inviting people to a private conversation on the site, except its for being able to update a download. Its not required, but it would be useful to have. Thanks.
