A screencast for the online marking tool (built using TurboGears and AJAX) is now up. It's a very cool tool --- I'm really looking forward to seeing how students and TAs react. I've also relocated the DrProject screencast to the department's server in order to reduce the load on ours. We're just days away from the 1.1 release, with performance enhancements, web-based administration, tag clouds, and more --- stay tuned.
