Question concerning trivia question errors I made...

I recently harped on a user who had submitted questions in the trivia function for not putting the game the question related to in their trivia questions. I then went on to make the mistake on one myself.

I cannot find a question edit function, though. My question is three-fold:

1: Is there a way to edit questions?
2: If not personally, is there anyone who can modify one for me?
3: Is there a way to at least show what game a question concerns so these nebulous "Who is the final boss?" kinds of questions don't cause so much trouble?
