git - Adding to someone else’s pull request on a GitHub project that I do not own

Question

Is it possible for me to add commits to someone else’s pull request on a repository where I am not the owner?

e.g.

User A owns Project X.

User B forks Project X, creates a feature branch, makes some changes, and submits a pull request.

User C likes the pull request, but would like to make some modifications to it. (FWIW User C already has a fork of Project X, so is unable to easily fork User B’s fork).

Can User C add commits to User B’s PR?

Answer 1

You cannot add commits directly to User B's pull-request unless you have write access to User B's fork. You can, however, make local additions to the pull-request, by just fetching the pull-request branch into your own local repo (assuming the url for B's fork is public).

I'm not sure if it's possible to do a pull-request into B's fork since your own fork is from A and not B, though.
