Your sponsor may want to change his sponsorship to be anonymous, so that those visiting the website will not be able to see his/her name. The administrator can make this change via the back end system.
How to get there:
Login to the Wizathon account.
Click on the "Sponsors" tab.
What to do:
Locate your sponsor by scrolling to his name or typing his last name in the search box.
Click on the first action item, "edit" (pencil icon).
Click on the "Anonymous" check box.
Click "Update Sponsor" to save your changes.
This sponsor will now be listed as anonymous in parenthesis, next to their amount.
