Complex scoring makes for headaches on your part, especially as the league gets larger. Whether you use off the shelf software, your own computer, or a napkin and crayon, scoring the league will take time on your part. And you can count on having at least one scoring error per season, something about the law of averages I think, but eventually you'll get one wrong. Creating The Specifics Now that we've established that simple is better, your first job as a fantasy sports commissioner is to create the specific rules for your new fantasy sports league. The first thing you need to decide is how much you are going to charge members to join, and how you will split the winnings, unless you are creating a free league.
Language is very important here.
Try to use language that is straightforward, friendly and easy to understand, no matter who is reading. While your rules should be exhaustive enough to cover most likely scenarios, don't over do the details. Remember, your members want to have fun, and enjoy their favorite sport, not decipher some 10 page rules document. However, once the rules of the game have been established, you must assure that all members strictly adhere to them. It never fails, and you can count on it, in fact, plan on it.
