Custom User Fields
Additional user information can be captured in Custom Fields, which apply to all users on the site level. Common uses include adding other email addresses or user specific notes. Custom Fields can be created from the Administration Tab by the System Admin user.
All custom user fields will be shown on the bottom of “Add a New User” or “Edit a User” pages.
If made Visible to End User, this custom field will be editable by the end users from the My Accountpage.
Is Editable By End User? option determines whether end users are going to be able to edit this information. When this option is disabled, users are going to be able to see the data entered into this field, but not be able to edit it.
