Voting starts in March for the Drupal Association Board election.
The site is running a vanilla Drupal 7 (upgraded from 5 -> 6 -> 7) version, added are some custom modules like pathauto, and also some inhouse development is done to integrate some features. Next year (or season), which means 2012/2013, we will implement Drupal Commerce as primary ticketsalessystem.
Because of the flexibility of the framework, the modules (ranging from meeting-arrangements to fullblown e-commerce), and the fact that the performance of great works of art lends itself very well for being communicated by an open and free (as in speech) medium!
The project, or choir, has been established to perform the works of Johann Sebastian Bach (and/or his collegue composers) on frequent bases in the Netherlands and abroad.
