It would be nice to have the ability for non-login users to go back to their registration and make an update. Not all users wants to create a login but they want to register for an event. Some website require users to create an account to register for an event but what about those who doesn't want to create an account? They would simply not attend your event if you force them to create an account. This feature will cover those who don't want to login and/or create an account to update their registration.
The link to update/edit registration can also be added as a Tag in Email/Messages in email notification template.
