A Wildcard is a URL in the TopScore platform that dynamically updates depending on which user is accessing it. If they have a profile set up with an organization, when they click a Wildcard URL, it will redirect them to their profile page for that organization.
For example, the URL https://pittsburgh-ultimate.org/u/me will take the user to their personal profile page on this organizations website. You can change the URL to reflect any organization, and this is useful for directing registrants or other users to their own profile pages for specific reasons.
For example, if there are age restrictions on an event and a registrant does not have their age filled in on their profile, they will not be able to complete the registration process. This would be an excellent opportunity to utilize a Wildcard link in the registration flow to encourage them, and all other registrants, to fill in their date of birth on their profile.
