Change "base repo" for GitHub pull requests
Is it possible to add a base repo to the list?
No, not by yourself.
Github only lets you do pull requests on forks it knows about, and offers no way to register two repos as forks of one another later on.
You have two options you could try:
- Contact Github support at support@github.com and describe your situation (briefly), including your username and the two repos involved. If you ask them for it, they might be able to add the "fork" status to your repo and thereby allow you to generate a PR
- Bypass Github for the addition of your changes: Git is not dependent on such things as pull requests, you can just contact the other project and ask them to merge in your changes. This can be done in several way, you could, for example, provide a patch of your changes, or they could add your Github repo and merge or rebase your changes.
