This is very easy and can be done via the confirmation email.
Firstly, the guest should find their confirmation email. Once they've located that email, they should click the MY DETAILS button, which will take them to their guest registration page.
If the guest never answered their registration questions when they signed up for the event, they will be immediately directed to the INFORMATION SUBMISSION window. They should choose their answers, then press SAVE YOUR ANSWERS.
If the guest submitted answers when they signed up for the event, but wants to change their answers, they will land on their guest registration page after clicking the MY DETAILS button in their email. They should click the hyperlink contained in the word 'here' to edit their answers.
The INFORMATION SUBMISSION window will appear. The guest should choose their answers, then press SAVE YOUR ANSWERS.
