What I see is an inexperienced developer who instead of systematically debugging the issue keeps trying random stuff hoping that it will somehow work.

If you have an email workflow that you like then something like rss2email might be an option. You simply feed your incoming rss into your email. You’ll want to auto-tag (or otherwise organize) these emails to keep them separate from regular emails. Then you use your usual email tools to organize them further.

I’ve been using such a setup for the past 15 years.

After typing in a bunch of programs on my 1KB Sinclair ZX-81 I wanted to understand how they worked and wanted to make some of my own.

Go with the frontend kept as simple as possible.

Personally I am comfortable with that as long as there is a public git repo. An issue tracker is the one thing I’d miss the most. I think how well this goes down will greatly depend on the project’s target audience.
notmuch is a project that I follow closely and very occasionally contribute to that works this way.

Already moved in the sense that I am not creating any new projects on GH. I am rehosting old projects opportunistically. No plans to get rid of the account unless GH does something really messed up.
