We've undergone a big update on the site, moving from our original, good old Moodle 1.9 server to Moodle 2.3. The upgrade path was filled with potholes with no short cuts in site. After quite a bit of work, our IT wizards were able to move all of our old courses into the new system without the loss of any data or activities.
With the new software comes a bit of a new interface and some minor differences in how users and course facilitators get things done. We hope the change doesn't cause any issues for you.
