I have a main repo that is only private and I have some peoples with a fork of this repo.

When someone create a fork of my private main repo I should have admin access that is not deletable to there fork repo. This way if I want to delete the fork or control what is done by this fork I can manage it.

I have an employe with 2 forks from my main repo and this employee is not working for me anymore. So I would like to delete theses 2 repo but I don't have access.

Thank you
