In most web browsers, clicking on an email address link on a website will trigger a client like Outlook or Entourage to open, instead of your GoogleApps@Brown account. There are several ways to configure your browser to use GoogleApps@Brown instead.
The easiest way to set up GoogleApps@Brown as the default client in Chrome is to install an extension called Send Using Gmail (no button). For instructions, see:
