Please add a field for guest nickname.
A high percentage of guests have nicknames, and it would be good to be able to call them by those in messages.
I'm surprised nobody else is upvoting this one. When guests use their middle names or nicknames instead of their first names, like me, I want all my messaging to address them by that name. Especially with no middle name field, I am left to having to write in notes what their real names are and then put their nicknames in the first name field.
I agree with you! A nickname field is definitely needed. So many folks don't go by their full first name and it would be nice to "get it right" in messages to them, while also maintaining accurate records of their full legal name.
