I submitted a 4v4v4v4 run. My friend that I played with didn't have a speedrun.com account but after the run was verified he made one. Now on the leaderboards it just says his name and it doesn't link to his account. Is there any way I could edit it to link with his account?

Pretty sure you just have to edit the run, and submit it without changing anything; that should link OhMati to the run. Note that it will send the run back to the verification queue.
