Where does information about my collective relationships (i.e., my roles) appear on the website?
Your user account in the Auth app (http://auth.opensolaris.org) contains information about the collectives with which you are associated. Click on ‘Collectives’ in the Menu list on the left side of the page. The page that displays (http://auth.opensolaris.org/collectives.action) will show the roles you have in collectives on the site.
