This is far from urgent and likely an implementation nightmare but...
I'm co-GMing a game and we seem to overwrite each other corrections frequently :(
Is there an auto merge changes (git-style maybe) that could be considered in the very long run?

Eek, I don't know about a git style, but as I never considered this situation, I never implemented something. Instead, for the more immediate (v2) situation, I can do a thing where when you try to save your post, if the most has been modified since you started editing, it'll warn you and show you the updated post. I have no idea how I'd do the diff part...

That could work (as long as the warning does make you loose your corrections :) )
I have no idea how that is done, is it python? i may have a look around and see if there is code available
