How can you help Joomla! development?
There are a variety of ways in which you can get actively involved with Joomla! It doesn't matter if you are a coder, an integrator, or merely a user of Joomla!. You can contact the Joomla! Community Development Manager, David Hurley, to get more information, or if you are ready you can jump right into the Joomla! Bug Squad.
The Joomla! Bug Squad is one of the most active teams in the Joomla! development process and is always looking for people (not just developers) that can help with sorting bug reports, coding patches and testing solutions. It’s a great way for increasing your working knowledge of Joomla!, and also a great way to meet new people from all around the world.
