If We Attend Classes Tomorrow, Then Don't the Terrorists Win?

This e-mail was sent to many, many people at my college today:

Students and Faculty, as president of [******], I have always kept the educational
standards of this university at a high priority. However, when the welfare of the
student body is concerned, a higher priority takes precedence. Therefore, due to
circumstances beyond my control, classes will be cancelled for Thursday, March 6th.
Classes will reopen the following Friday under the normal schedule. Assume
scheduled activities for Thursday to take place instead on the next day at which
that class is scheduled.

Along with this in my inbox were seven other e-mails proclaiming this one to be a hoax. Thank God, because the poor grammar and diction would never have given it away. "Reopen"? What is this, Wal-Mart? And can anyone translate that last sentence for me?
