I once had a teacher who said that there is no such thing as a dumb question, because there's someone else who is dying to ask the same question, but isn't brave enough to ask because he/she thinks it's dumb. So a lot of useful questions could go unanswered because so many people are afraid to ask. Just ask away. The question isn't dumb, probably something someone is wanting to know the answer to, but is afraid to ask. We can't always guarantee an answer, but someone here will certainly try. Melanie
