Maintenance, implementation, and hosting

The content of the site is maintained by the staff of ALT, and by individual ALT members with editing rights.

The site is implemented using two Open Source applications - Drupal and CiviCRM. Hosting is under a commercial contract between ALT and Positive Internet Ltd.

The site was initially developed for ALT by Futurate, who won the tender for the work during early 2010. We thank a large number of individuals who have contributed ideas for the site and observations about its operation, including Andy Carter, Dan Barker, David Jennings, Dick Moore, Doug Belshaw, Frances Bell, Gill Osguthorpe, Greg Benfield, Harry Greiner, Haydn Blackey, Imogen Bertin, John Bourne, John Slater, Karen Ver, Lucy Saxton, Maren Deepwell, Mark Berthelemy, Martin Hawksey, Martyn Bailey, Matt Jukes, Matt Lingard, Mike Sharples, Nick Jeans and Stephen Harker.
