We're using WP Members to manage user registration and settings, and I'd like for members to also be able to set up/edit their display name when they register or update their settings. This is already a native field in the wp_user database so I don't want to make a new custom field, I just want to be able to edit that particular setting using the WP Member front end.
Can this be done? I thought perhaps adding it to the wpmem_fields_options_arr in wp_members_install.php, but then thought maybe I'd just better ask. ;)
