[Callers] dance guidelines

During the past month, I've had more exposure to dance guidelines and people wanting to write dance guidelines than I've ever had before. What I'm talking about is guidelines that the programmer/organizer of a regular dance series provides to callers who will be calling at that dance. I've found some to be very helpful, especially when I've never been to that dance. Others provide way too much information and almost feel like micromanaging. So, my questions for you all are: 1) Have you ever received a set of such guidelines (or sent them out from your dance), and if so, would you be willing to share them with us? 2) As a caller, what information would you like to have included in such a document? 3) As a dance organizer, what information would you like to convey to incoming callers? 4) How much detail would you like such documents contain? Thanks, Lynn
