After I submitted our team quiz, it disappearexd from the Team Quiz board, but is still visible in the list of my quizzes. If I now want to make a late edit (NO, I don't actually want to do it, and know it is a bad thing that send the quiz to the end of the queue, but I want to klnow in case of future 'emergencies') I don't see how I can do so. I cannot edit from my own quiz list - get the message about checking it out even though I am the project manager - and it isn't visible for checking out. Can it be done?

You can open it up from your quiz list after it goes online. So I guess while it's in submission limbo, you could either message a category editor about a change needed, wait for it to be rejected if it's something big than an editor will notice, or make your small correction/addition after it goes online.

I rather suspected as much. I certainly hope Inever need to know, but it's good to be prepared!
