Google has updated the interface for Denison’s Google Apps .  In order to access your Google calendar, drive, sites, contacts and search, you need to click on the icon of small squares next to your email account name in the upper right corner of the screen.  If you click on the squares, a window will open and you have the option of opening a window for one of the other Google tools.
