Contribution mechanism in Nest

Sorry if it is an obvious question, but I don’t see the equivalent of fork/pull request of github in Nest. Is it exists? If not, is it planned? Would it have the same form of github, or something completely different? And what is the current way of contribution to the repositories on the Nest? Email?

It exists, and I find it better than pull requests: you can attach loose patches to discussions, by pushing them to a special channel whose name is the discussion number.

Since these (fake) channels are always empty, you probably want to compare them with main, which you can do with pijul push --to-channel main:65 (for discussion number 65), or simply pijul push --to-channel :65 since main is the default channel.
