//As a campaign participant, if I register privately, I want my username to only be displayed to me and the campaign organizers in the 'more details' moda;, so that I can register with confidentiality.//
**Acceptance Criteria:**
* If a participant registers privately, their username should only be displayed to themselves and the campaign organizers
* The total number of privately registered participants should be displayed
* The total number of privately registered participants should be displayed to non-organizers (i.e., any participants or anyone who visits the page) if the full list of participants is displayed
** For example: There are 4 registrations total. 2 are public, and 2 are private so display that "2 are private." However, there are 50 registrations and 10 are private, we should not show the number of private in the truncated list, but only show that number in the full view when the user clicks on "View all," when you go to the EventDetails page.
* Organizers see a padlock icon beside the usernames of participants who registered privately and the total number of such participants at the bottom of the participant list
* Participants see only the total number of such participants at the bottom of the participant list
