This website was also built to function on propriety back-end. I used this to create multi-level user access, allowing restricted areas to be created; similar to putting content behind a paywall. The challenges of this site included several redesigns, but ultimately we were able to settle on what the user wanted.
This site pleased the client immensely, as now he had an online media gallery of sorts to display his work and allow others to download it. Distribution of his work at that point increased greatly and he was inspired to do several new works as a result of the traffic.
