I upgraded www.umass.edu/wld from Drupal 6 to Drupal 7 / Omega 3 theme and gave it a fresh design. It went live in September 2015.
An important feature of this site is the sign-up online process. I used the sign-up module and Shibboleth integration. The sign-up form pre-populates with data from the University's database as a result.
Due to a limitation in the signup module, I used hook form alter and added node object $node field_starts to fetch the workshop date field and include it in the admin email (in template.php).
Another interesting development feature is the Wait-List form. After login, the user selects a wait-listed workshop (envelope icon); the title and node path are then passed to the form. Used webform, current-page query tokens, rewrite and key/values in view.
