Any member of any given ESN section can check other sections' accounts at accounts.esn.org and find general information about the section as well as a list with all the volunteers in that section.
But oddly, if that person is added to a certain section but not given any particular role, or s/he requests to be accepted in that section and is left in an unaccepted state, the ammount of information that's accessible to that person is not increased, but rather reduced, as the member list of that section is no longer visible.
While I can see why no more information should be accessible, I can't come up with a reason why just by requesting to be accepted to a different section, or be accepted indeed without a particular role, should reduce the ammount of information you can access to.
Maybe it's a bug, or I may as well be missing something!
