Unsubscribe Page "Flexible subscriptions" Link not applicable to non-logged in User

The unsubscribe page (as reached from an Invite Email and perhaps other methods... e.g., "http://project.userecho.com/users/11/unsubscribe/project/19647/?token=t" has a last line that reads:

• Also you are able to change your subscriptions more flexible from you account here.
  (i.e., URL: http://project.userecho.com/users/11-tgauchst1/notification/)

• For a non-logged in user (i.e., a user accessing via Token), this jumps to meaningless page: http://project.userecho.com/users/11-tgauchst1/topics/
