This is not a long list at all, and some of these communities you are mentioning might be a good for https://indiehackers.space. The best way you can help me now is by signing-up to https://fediverser.network and adding the subreddits that you are missing and use the “request a community” for the ones that are missing.
I also went ahead and created [email protected] if you want to get started. :)
