The location of the link to access the Jury Portal varies depending on the site theme for which your SparqFest site is configured. Typically, you will find it either in the page footer or in the profile menu after you login.
If the link is at the bottom of the page and you are not logged in, the site will first prompt you to login and then redirect you upon successfully logging in.
If you click the link and are prompted to enter an invitation code, then you are logged in as a user who does not have proper access to the Jury Portal. Contact the festival director to gain access to the Jury Portal.
