Once inside the system, notice the links on the top-left corner of the screen.
All notice types you subscribe to are listed at the top. Clicking on them takes you into each interface.
Inside Site Notices, you also have links to Site Notice Report and Opt-Report.
In the top-right corner, you'll see your name and your company name. Click on the gear icon to display a drop-down that gives you access to your account (My Account - name and email address), as well as a Sign Out link.
Note: You'll only see the Admin link if you have Administrator rights.
