In recent weeks, Michael and Ngoc have updated screenshots and a lot of the content at our 100+ page CMS-user help website, http://userhelp.silverstripe.com.
This brings the material up to date for our upcoming version of SilverStripe 2.3.0, and is part of our overall efforts to continually improve our documentation.
Updates to the downloadable .doc and .pdf versions of this help will come later this month.
