You can't, but the admin can. Go into one of the excess messages, and inthe first post you made, right below your name is an exclamation inside a red triangle that is for reporting posts to the admin. click that and it will give youa box to tell the admin that you double tapped the submit button and they can delete the excess/multiple subjects.
