We just received a mailout from Martin Dougiamas, the creator of Moodle. Seems there is a new version of Moodle available. Moreover, due to security issues, site admins are advised to upgrade ASAP. So that is exactly what we have just done. More info:-
All the upgrades were successful and we are currently RSync-ing the changes to a remote server.
As an aside, all the Moodle installations on the DEOSS Community Server now get automatic virus checking on uploaded documents and a built-in spell checker, as standard.
