The 9th Annual Youth Service Institute (YSI) will take place October 17-19, 2012 in Houston, Texas. The site I built for YSA uses the COD Fusion Swimmingly theme and v1.1 of the COD Support Modules (Beta2 of the installation package). Customizations include changing the sidebar color to green, a custom header graphic, as well as several added modules that enhance menus (menu breadcrumb/ token/ per role / parent actions modules), profiles (one page, category weight, checkboxes, tokens), Ubercart (Coupon, ECO, Views, Free Order), and add weather.
In addition, while the major functionality of having paid signups is the default, I instead configured the registrations as Ubercart products to be bought and just used Signups for specific Schedule Items (called Offsites) I wanted people to be able to sign up for. This necessitated changing the Views for Community to use an Ubercart:UID relationship. The main changes that were made were to only show UC status = "registration completed" and to sort first by existence of photo and then by newness of user. The View was cloned to create a separate page with exposed filters for attendees to find each other.
Also, a custom profile-listings.tpl.php was set up to prettify the profile listings, which are seen anytime someone clicks on a profile field (such as interests, grant program, job title, or organization) ,to make them more interactive.
