COLI has produced several video tutorials for students on using Gmail.
The first tutorial is showing students how to create a signature in Gmail, which can be viewed by clicking on this link. Faculty and staff know the importance of an email signature, but sometimes students do not. As such, this video quickly explains why an email signature is important and some of the information that should go into an appropriate email signature.
Next up, we also have a video on how students can quickly organize their Gmail by using Labels. Click this link to watch it. This can help students quickly find course emails and other important emails.
These videos and more can be found on the Google Apps for Education – Student Resources wiki page.
