Logged in users set to be able to reg. new site, but no link visible

I have multisite set to allow site registrations by logged in users. But, if they don’t already have a site, they log in and see just the wordpress news widget and the ability to change their profile. No way to make their own site.

I added a custom dashboard widget with a link to wp-signup.php and this works but it seems like there should be a better solution.

Users on my multisite are authenticated by Shibboleth and an account is automatically created.
