Several churches are using or are interesting in using the Planning Center SAAS service for scheduling, etc. In our Churches BOF (@see http://groups.drupal.org/node/299228) we had at least 3-4 people express interest in creating some kind of Drupal integration. I would like to start a planning discussion here that could eventually lead to a sandbox module which could lead to a public release of a module or feature for Drupal.
I went to the Planning Center website and asked for some kind of API documentation and/or a test account if they have one. I will see what they say. I don't know enough ab the Planning center to know exactly what it does and what integration with Drupal would look like. So maybe we can start an open thread here and do some pre-planning on what the module could actual do to make it easier to integrate PC with Drupal.
