An event can honor donors by scrolling their name on participant's donation page. When a donation is made in a Kinterathon, the donor can select to display their name, anonymous, use a nickname or choose to use someone else's name. The default that displays however, is the name of the donor.
Unfortunately, the default cannot be changed and will always be the donor's name. The donor can choose to use a different name or use anonymous after making the donation.
