These days you need to be really creative with making cool MSN screen names, because most are taken! First, think of things you like to do. If you like sports like baseball, maybe start off the name as BaseballDude, and add various numbers to the end. Do you have a favorite book or movie? You could start the name off as the title. You could even combine titles. Such as "Twilight" and "New Moon",
. your name could be "TwilightMoon". There are even websites where you can randomly generate a name. Whatever you choose, do not pull your full name as an MSN screen name, it's a security risk.
