As part of an institution wide brand refresh, the Australian National University has rolled out an updated skin for Sakai, as well as a number of portal, kernel and tool updates and modifications. The next phase of our Sakai implementation is an upgrade to Sakai 2.8 which we will be undertaking later in the year.
Our installation, dubbed Alliance is available for public use (however you must be invited to a site) and we host a number of sites for the Sakai community including the AuSakai User Group.
You can see the new skin in action here: https://alliance.anu.edu.au/portal
For any detailed information on our upgrade, toolset or modifications, please feel free to contact me directly.
