Post editing by anyone option

Allow for the ability to edit a post to be editable by anyone. The author of the post or a sysadmin could have the ability to select a post as “Editable by all”

Here’s an example use case:

We have a development channel in Mattermost where we (developers) schedule 4 hours of our work week for doing research on new topics/languages/etc. We need to schedule the times when we’re going to do our “study time” but we need to schedule them at different times so work is still being done. It’d be beneficial for anyone to see the post and update their times for that week or to reschedule etc.

This could be an interesting Idea and thought I’d throw it out here to the community for yay or nay on the topic.
