A phishing email from "IT Service Desk" has been making the rounds today. It asks you to click on a link to "Validate your account." Do NOT do so. Instead, if you haven't already deleted it, mark it as phishing.
Below is an example of this email. Note that like similar ones, the subject is blank, it has grammar errors, and contains the threat that "You will not be able to receive new mails until you Re-Validate your Email Account." Read more about phishing at http://www.brown.edu/go/phishing.
