We have been running the legacy 1.X series of Moodle for a few years because the new 2.X series is quite the overhaul and redesign of Moodle. The developers of Moodle are going to discontinue releasing security updates for the 1.X series of Moodle this fall and I have updated our copy of Moodle to the latest version before this happens.
Course roles have changed a little. If you are unable to modify a course that you believe you should be about to modify please contact us! It is likely that we need to (re)enroll you as the teacher of the course.
