Joomla Days West 2010 was a milestone in the Joomla Project. held at eBay's own campus, was the biggest JoomlaDay yet. Both Microsoft and eBay have signed the Joomla! Contributor Agreement or the JCA. The JCA is the agreement put in place before code is contributed to the project and two of the largest companies in the technology sphere have now signed the JCA. There also were many new faces at the event. Jomsocial was there, showing off a FaceBook style social networking tool for Joomla. This one extension is perhaps the biggest and potential greatest thing that has been produced to extend Joomla.
