I added "My Review Requests" link to base navigation bar, which links to /users/<username>/ for the current authenticated user.  This makes it easy to find your own review requests, rather than having to search on your username or scroll through a long list of "submitters".  I also added this link to the base iPhone page.

This link does not appear for non-authenticated users.

Tested with Review Board r1554 in Firefox 3 (OS X).
Tested with both authenticated and anonymous users.  Tested on dashboard/, iphone/, and various other pages.
Ran unit tests, and created a new test (ViewTests.testDashboard5).
