One of my favorite parts of StackOverflow and the StackExchange family of sites is the feature to suggest edits to a post. It allows posts to become better and easier to read.
Would it be possible to add something like this to discourse? A forum user could recommend edits to a post. These edits could be only accepted and added to the post by the OP or a forum admin.
If a user sent a spam suggestion, it could simply be declined by the OP or staff.
