I created a quiz under the topic Nostalgia, called Awesome 80s, on October 11 and it still says "Will be online shortly" after all this time. What I want to know is, why is it taking so long for it to appear online?
All the other quizzes I created showed up the day after I created it.

I'm not the editor for that category, and I haven't seen your quizzes, yet, but here is a past thread that might help you with your question.

I don't know if any of these apply to your quizzes, but this is an excellent thread to review, too - just as a quizmaker:

I too was wondering why my two quizzes were taking so long, so I checked out the thread that Linda1 suggested, and lo! TonyTheDad who complains of the same thing, is now one of the editors of my quizzes, that haven't yet appeared! Hang your head in shame TTD!

But, Phillipa! Look at the answer that he received at the time! Still true - even for him as an editor.
