Someone registered for a match using my account

I went to confirm my registration in a match that I’d entered last week, and found I’d been moved to a different squad, and someone else’s registration appears on my dashboard? May or may not be related, but he’s in the squad I’d originally signed-up for.
Would the MD, or anyone else, have that level of access, to move me to a different squad, and/or register someone under my account?

The MD can move anyone around on their match.
As far as registering someone, they could have added somebody and accidentally inserted your email for that shooter. It would then show up on your dashboard.
I would suggest contacting the match director.

Thanks. I’ve already requested that the shooter be removed from the match, and informed the shooter they will probably have to reregister, so it will hopefully be rectified by the MD.
