When that becomes a new thread’s OP at the appropriate time, I’ll add things like common objections, different official and fan sources, commonly edited changes, unique edit approaches, etc. I’ll add information about the context of the movie which might help focus an editor on their personal priorities, and list a few different goals that other editors have had. Anything that makes the process of actually thinking up new approaches and ideas more likely to occur.
That sounds fantastic (but also a bunch of work)! I foresee a lot of neat new ideas coming out of these threads, which editors can reasonably easily find and incorporate into future fanedits, even if the collaboration thread itself doesn’t ultimately produce any kind of final product - like how my Palpatine face change thingy wound up in Octorox’s ROTS edit some time later.
