The WordPress project is 100% user driven and depends on volunteers to make it all happen. From the core code to documentation ... translation to support ... plugins to themes ... WordCamps and Meetups - - everything that happens around the WordPress.Org project happens because of users who volunteer their time. WordPress is 100% free for all of us to use to run our web sites; run our businesses in some cases - why not consider taking some time out of your day to give back and volunteer some of your time to WordPress?
