Using Moodle - Teaching with the Popular Open Source Course management System by Jason Cole and Helen Foster is published by O'Reilly as part of the Community Press series. It can be downloaded for free. Cool
The first edition of the book, written by Jason Cole and released in July 2005, is based on Moodle 1.4. The second edition, released in November 2007, has been updated to cover all the features in Moodle 1.8, such as the new roles and permissions system, blogs, messaging and the database module.
Really bad news for all of who have used Ning free services!
Jason Rosenthal: "We will phase out our free service. Existing free networks will have the opportunity to either convert to paying for premium services, or transition off of Ning."
