Many people have a formal first name and a less-formal or actual nickname they go by. I'd like to maintain my client list with my contacts' actual names (e.g. Charles), and be able to address them by their familiar name (e.g. Chuck) in emails. Otherwise, I sound stodgy or, worse, my emails sound canned. I know they ARE canned - that's what this is - but I don't want them to SOUND canned.
