I've been thinking about this for a while now, what's everyone's opinion on creating a GitHub repo to allow people to upload subs? We could add some basic organization to it to differentiate the different types of sources (Whisper, hand translated, CH to EN...etc.) and even allow users to submit PR to improve sub quality.
That is too complicated, unfortunately. There should be a better source or UI for crowd edits, but Git specifically is both too complicated and I don't think Git version of merging will work well with SRT files that have each line given a specific number.
