The Chicagoland Skydiving Center website is one of the most feature rich, biggest sites we've ever developed. It was a great experience working with CSC. They really pushed us to be creative with the design and the code.
The site features a full Content Management System that allows them to update their own content. On top of that we tied the site into weather broadcasts, Flickr, Twitter, Facebook and YouTube.
The photo galleries pull images from their Flickr account every 6 hours. They simply use Flickr to upload photos and create photo sets to organize them. We then pull all that information into their site. Same thing goes for YouTube and Twitter, if they update those accounts their website is automatically updated.
Another feature with this website is a WordPress blog that will allow the owners and staff members to post updates and other skydive related stories.
