After participants are registered, there may be instances where the user needs to request edits to participant information or collect additional details. RACE RESULT 12 addresses this need through the same Registration Forms tool but set into the "Self Service" type, available for both Single and Group usage. This feature generates a unique URL, called ChangeLink, which is sent to each participant. The ChangeLink allows participants to securely access, review, and edit their information.

In other terms, the ChangeLink is nothing more than a URL loading a registration form set into the "Self Service" type, with some input data pre-filled with the participant's information. The login functionality is not necessary to use for the Online Self Service.

The ChangeLink URL is created using the ChangeLink() function within the software. The URL comprises the self-service form name, a unique key for the form, the participant's ID, and an additional unique key to ensure security and privacy.
