3. If you’d like the member to be able to modify the custom field themselves, select Read/Write for Member Permission. If you’d only like them to view the custom field and not be able to make changes, select Read Only for Member Permission. Disabled Member Permission would not show the custom field to the member at all.
4. Members modify these in the Member Information Center under Account Settings->Company Information->Additional Information.
