Developer Network™ 
We are embarking on a massive effort, a Joomla frontier.
Never before has a group of industry professionals banded together in the Joomla world to collaborate with the community on a common goal.
There is always a great deal of Joomla! development activity underway and communicating with other developers in the community is essential. This site is a resource for anyone looking to build or maintain software based on the Joomla! platform.
