Invite Other Members to Post Collab

[XFFA.IR Bot]

This suggestion is to allow posts to be written collaboratively, where multiple users can work on a post or reply at the same time in a shared, synchronized post editor. The user creating the post would have an option to invite other users to join the post writing session. If accepted, the users could write a post together and the original post creator can post it when it's done. Posts made this way would show all of the involved contributors in the thread view instead of one author.
