The revamp of OMACworld was brought about due to the old site being a basic "billboard" style site that was very difficult to update and maintain. I chose to use Drupal as I thought it would be easiest for our mostly non-technical school owner to be able to use (although I haven't gotten him to do anything more than write a single blog post so far...).
I've used CCK and Views to create branch locations, class schedules, and lists of masters/instructors. Also used the Event module to create a couple of different kinds of events (Camps, Tests, Competitions). Used Nice Menus to create easily modifiable menus. Currently almost no custom coding required.
Future work includes:
* using carousel/slide show for
** shortening the current static images that link to the discipline pages
** adding "excitement" to the current stories instead of basic blocks
* Fixing the carousel with the videos to look correct
* adding Ubercart-based webstore to allow for event registrations (this is taking a lot of work, because it needs event, web form, and UC)
* modifying the Location CCK content type to handle our international schools (currently using things like US Zip and US Phone, which precludes inserting international addresses)
