This has cut the turnaround time for the student to get feedback from several days to several seconds. I'm still perfecting the script. I'm working on getting it to write directly to the student's records. It will first check to make sure the student is enrolled in the course, then check to make sure the student hasn't already submitted that lesson already, then it will score the quiz. It's really nice because it allows you to see a new post before most other people, giving you the option of removing an unwelcome message before it's been seen by too many others.
Instructors find it handy if the web board is only posted to occaisionally.
They don't have to check it for new posts every day. I recently added a different feature to the web board. There is also a form to remove your e-mail address from the list. Just for funzies, I wrote a script that can do an almost realtime chat. It works along the same ideas as a web board, but the script is pretty different.
