I have been preparing to start a group through some missions. I am going to require that everyone stay in character. One of the issues is calling each other by character name. I have ran several things through but just can't seem to come up with a solution that fits the genre. I have considered those soppy "My Name Is..." stickers and computer generated labels, even considered having them write their names on their foreheads with a grease pencil. Any ideas out there?
