When you create a profile on MINDZ.com you have the choice to decide who can view your profile. You can choose the option My profile is visible to everyone or the option My profile is only visible to my friends and others who participate in the same Circle or Plaza like me. In the first option, everyone can view your profile. In the second option only the people who participate in a Plaza Circle or Event, in which you participate too, can view your profile.
The list of attendees for an event you see when you're not registered, shows only the profiles that have chosen the first option. When you register and are logged in you will also see the profiles that have chosen the second option.
