Today I’ve faced problem with syncing two github repositories. Yes, I know, I shouldn’t keep two, but sometimes it’s difficult to avoid. Anyway, the problem is super easy to solve. It’s enough to edit `.git/config` by adding new remote:
url = email@example.com:user1/repo1.git
url = firstname.lastname@example.org:user2/repo2.git
Of course, more than two repos can be added. Then, after next push all repositories will be synced.
