Welcome! Everyone is nervous to begin with! So, take your favorite hot beverage and wander on over to the New Mystery Shoppers area of the forum. there are about a dozen topics "pinned" to the top of that area for you to read, read, read. They will put you on the path to a good start and will probably also help you know what questions to ask next.
