I’ve heard from a lot of people that they “had a friend who was mormon”, or “used to work with a mormon”. A lot of people still do. If this is the case, and if you’re comfortable with them, you might try approaching them and telling them you have a few casual questions about the mormon religion. Chances are they’d be happy to answer them, and the information you’ll get will be first-hand from someone you trust.
If not, please do feel free to post your questions here.
