CMS Made Simple is developed by the community. Welcome to participate!
We're always looking for templates or design ideas. We also have a module API that's just waiting to be used. And you can join the RC Team to test out release candidates before they go live to the masses.
At the moment the documentation is being written. We gladly receive contributions to that work! See http://forum.cmsmadesimple.org/index.php/board,16.0.html for more information. To use CMSMS in other languages, we welcome translations of the core, as well as of extensions and documentation.
You can contact us in #cms on irc.freenode.net or hit the forums to get involved. You can also read more about how to participate by browsing the menu on the left.
