At top right of Community, when we're logged in, we see a block status indicators.
Username, pulldown, Avatar space, Bell icon, # of unread Notifications, space, Envelope icon, # of unread Inbox Messages, Help.
All are linked, except for # of unread Notifications. This is inconsitent with the # of unread Inbox Messages, which is linked.
I find myself wondering why a non-zero numberical indicator won't click through to something as it does just to the right and on most other sites with notifications.
