In the current version 1.0.1. it will display the first name and the first initial of the last name (assuming they enter “First Last” in the name field). It splits that name field up by spaces so below are some example of what could display…
User enters: Sally Seashore
Displays as: Sally S.
User enters: Mr. John Doe
Displays as: Mr. J.
User enters: Mary Ann Smith
Displays as: Mary A.
However, we will be adding your suggestion for allowing full anonymity on the front-end to our list of possible improvements in later versions. Thanks!
