It takes an entire community of people working hard all over the world to make a project like Joomla thrive. If you help write documentation, answer questions in the forums, report, patch or test bugs, share GPL-compliant extensions on the Joomla! Extension Directory, write core code, create translation files, run a Joomla! User Group, organize Joomla! Day events or participate as an active member in a Joomla! Working Group, then you are an important part of making Joomla! available to the world.
