could you check out my other question regarding pronunciation? i got one response back, but i'm not sure how reliable that was

I've checked for the pronunciation of Covey -- and have found nothing online. I'm sorry, but I haven't heard his name pronounced. I suggest you ask your teacher -- or better yet -- a librarian tomorrow before your presentation.

thank you for your help

You're welcome.
