If your quiz has been rejected and you need to get in contact with the editor, we're currently having a bug where the name of the editor who rejected the quiz is not showing up in the 'to' section of the note. If the editor forgot to sign the note with who rejected the quiz, I would suggest looking at the list of editors who edit the category your quiz was submitted to and sending a message to one of them asking who edited the quiz so you can contact the editor directly. (You can see who edits in the category by going looking at the category and then the list of editors will be under the list of subcategories under "Category Editors" with a smiley face in front of it.)

Also, try putting the quiz ID number or the title of your quiz of the quiz you're asking about in the subject of your notes so it's easy for us to see what quiz you have a question about.
