I put this under BC support because the design was handled by a designer I work with. While she works fall time with Gander Mountin, she helps with a few website customers on the side. This is one of her customers where she designed the site and asked me to build it out in Business Catalyst.
The result has been something easy to use for her to manage the site for her customer, including a recent modification where we used Categorized events to create an audition sign up page complete with reminder emails and follow ups automated by the built in features of the Events module.
With this design, I made the needed modifications to make is mobile/responsive of course, and they make use of a few other built in features of BC such as FAQs, forms etc.
