AFS NZ originally need a site for their Alumni to help rebuild connections, fundraise, organise events and conferences. There were also requirements for a library of old press articles on students exchanges.
This was followed by a request to provide them a similarly themed Pasikifa site.
This involved setting both Drupal sites to work with a single CiviCRM database.
We are currently working on setting up Chapter sites using Domain Access and a multisite implementation of CiviCRM. This will provide branches with limited access to contacts in their region, using the CiviCRM capability of adding people to a control group based on which domain they are using.
Chapters will also have 'intranet' features through Organic Groups.
