How not to do enrollment management

From The Chronicle of Higher Education:

U. of California at San Diego Accidentally Congratulates 28,000 Rejected Students

The admissions office of the University of California at San Diego accidentally e-mailed letters of congratulation and welcome to its entire undergraduate applicant pool, including 28,000 students who had been rejected earlier this month, the Los Angeles Times reported. Campus officials blamed the mistake on an “administrative error” that involved selecting the wrong database of recipients.

To be fair to UCSD, at the bottom of the article there's a correction stating that the students weren't actually mailed acceptance letters, but they were instead invited to a reception for admitted students. Here's a link to the full article. And this is not an April Fool's joke.
