As a library administrator, I want to be able to record a patron's preferred first name in the library's records, and use it to address the patron in various communications with them.
The user record will have a field added labeled "preferred first name."
It is a single field
It will be unlimited in length and allow characters and spaces
It will be a token to add to notices.
Given I am on the create edit user record
when a patron informs me of their preferred name
then I can enter the name in the field that appears under the required last name, first name, middle name.
Given that I enter the preferred name
when I save the record
It will display on the screen as "prreferred name."
Given that the patron's record already has a preferred name,
when they report a change
then I can open the field and edit it,
and then save it again
and then it will display.
