There are certain survey questions that you may have not want participants to be able to change themselves after they have registered. These include survey questions where each option has a limited number of times that it can be used before you, the administrator, hide it.
If a participant contacts you because of a change, as the administrator, you can update their answer to these questions.
How to get there:
Login to the Wizathon system.
Click on the "Participants" tab.
What to do:
Scroll down to the participant's name or type the first few letters of the last name in the search box.
Click on the first action item, "edit" (pencil icon).
You can then click on the "Profile" button (on the top menu, first button from the left) to see all of the survey questions answered and may change any of the answers.
