Introducing...

As a person who grew up with an 11 letter last name, 24 total in my entire name, let me tell you if you have unique names in your wedding party you better make sure the DJ knows how to say them. Writing in phonetically might not be all you need to do. This should be done in advance unless you want the DJ to stall while trying to figure out how the heck to say the names of your friends or family. Nowadays all kinds of first names are spelled weird, if so; just spell it the correct way.
