The coolest email feature ever. Call up a canned response anytime... or set up a rule to auto-send a canned response based on text in an incoming message!
This should win some kind of award for funniest and most useful feature: "Many of us have experienced the embarrassment of having sent a message without attaching the file we said we were going to attach. Turn on the Forgotten Attachment Detector in Labs, and you'll get an alert if you mention attaching a file but forget to do so."
From Emily Chang, gmail engineer: "I can see both my Labels and my Chat buddies at the same time, with one on the left and one on the right." In gmail, click on settings and then labs to enable this feature.
I wanted to do some specialized queries in gmail and found this very helpful. Incidentally, the "-" operator still works to remove specific types of results from your search... so you can search for mail that is starred but not from a specific user, for example.
Good directions for creating the Gmail "+" account for your students - in order to sign them up for other web services, such as edublogs. Thanks @gailhd for the link. :)
