How to Flag/Remove Your Own Dumb Trivia Question

Last night I put in my 20 for the Giant Bomb's trivia quest, but in one of them I made a stupid error, asking people to identify the only game in the Harry Potter franchise that was an RTS; I should have said RPG (Harry Potter RTS all the way!)
 
I would have hopped that enough people who got the question wrong (only 20% fluked it) would have flagged it and prompted it to be removed, but its still there for now. So apart from the small chance of actually finding the question, is there a way to flag your own question or delete it entirely?

I'd like to know the answer to your question too. Haha.

It would be awesome if you could simply edit them. Doesn't seem to be an available feature though.

As you haven't associated the question to any page I can't find it and delete myself. If enough people flag a question it gets removed so it'll probably happen eventually.
