Yep, it's now official (and I've been dying to brag about it for a couple of months!):

Atlassian, developer of software development and collaboration tools including JIRA and Confluence, has chosen Magnolia CMS to build ‘Atlassian University’, a state-of-the-art product training site, as well as a new corporate site.

More info at - hoping for a case-study to come up in the next few months !
