FrontRow You’re welcome. If somebody else backports it, you could test to see if it works – that’s the fun thing about Drupal: there are so many levels that people can be involved.
Anyway – glad you saw this reply, and I’m looking forward to the day when my bit of work will be able to help with your site.

The Drupal approach to this would not be to create a Drupal 6 module, but to create a Drupal 6 release of the module I’ve created. The code needs back-porting to Drupal 6.
I would be very happy to help this to happen, but don’t have the time to do this and to test it – at the moment. Drupal 6 will be EOL once Drupal 8 is released (around the end of this year), so my priority is to help ensure it’s fully ready for a Drupal 8 version. I’ve created an “issue” on the project issue queue to give people a space to work on a back-port and review each other’s work. https://drupal.org/node/2018653 If you want to join in with that, I’ll gladly help and support as needed.
