Since December 2009 we have been contributing towards an open-source project called Etherpad. Open source projects can be described as free software that is free to modify, use and redistribute. Etherpad has been the technology we have used for PrimaryPad. Today Etherpad Lite finally reached Version 1 which means it’s ready for download and widely adopted usage. We’re really proud of this achievement and we hope to support the project into the future.
