Can I see what events someone is the contact for?

Go to the member's page in the administration panel.  Scroll down the left hand column to the section WebCollect Roles.  If the person has an administrative role, and is the contact for one or more events, you will see a clickable link to the events.  

When you click on the link, a pop-up will appear with the list of events that they are the Email Contact for.  You can click on any of the event names to go to the relevant event page in the administration panel.
