"What's new" would certainly help my teaching.
Right now I get all new emails/postings/homework alerts as notifications (123 messages in my inbox yesterday from 22 students).
Due to the fact that each notification has a different number, I can't seem to set up a rule in OUTLOOK to bundle all new postings, emails, and "homework alerts" (like that expression - sounds dangerous) in one folder.
If there were a folder with only new items in the class system, I could then simply turn off the notification feature and still be assured that I have new information. My students also have problems with the flood of emails in the present system, too.
We all seem to agree that this would be useful, but I wanted to describe my hands-on situation.
