Either one of the other people helping me with contacts or I will likely write up a doc for how to integrate with contacts sometime this month (i need to make integratation simple for my school, so i need to make this functionality simple anyways). I'm really busy right now so i'm sorry i can't say when that will be out. Before we go for a "full number" release (i'm guessing at the end of this month), we will have the documentation done. Sorry, but i don't currently have the time...
