The majority of That Print Thing has been developed in-house by our web designers and we have been using it since July 2010 to power our own online shop which is the only way receive orders.
We consider That Print Thing to be in a BETA stage because we haven't added all the features to the system we plan to add and there is the occasion bug to fix. There are several features that we are currently developing that have not been made public and these will be added to That Print Thing subscribers as soon as they are ready for the public.
We aim to complete the majority of this work during January 2012 when the system will be brought out of its beta stage and users will move onto a monthly fee.
