Can you comment on it so I can assign you to that? I would like the following:
No need to open a new Forum post for each PR, you now have approval to PR anything in that list.
Collate all exercises that ONLY need a sync (so no code change)
For each exercise that needs a code change, open a separate PR
Link each PR in that issue (so I can easily open them when I have time)
You will gain some rep for doing this work.
Do not worry about the auto-closer, and feel free to profusely ping me here or on GitHub. I get a lot of notifications so double tagging works best (like Glenn did!)
