Your profile page has a complete listing of your roles as well as a break down of each circle and role you fill, with their purposes, domains, and accountabilities all in one place! It also shows your tags if you have any.
To get to it, click on your name or your organization name and select "View Profile" from the drop-down menu.
Note that others in your organization can see this same information when they look up your name in the GlassFrog search bar.
