Am I taking a quiz making a contribution...?

I swear I'm not a complete idiot.

Twice now (the other was likely a year ago), I've seen an entry have something with a question that I thought was a quiz and it turned out I was submitting something (and my guess is NOT likely to be correct).

They sent me an email with a confirmation (IMDb update receipt), but there isn't an option to edit or delete the information, this (editing or deleting) seems like it should be an option (even for people not making idiotic mistakes).

My 2 cents...

Thanks/sorry!
