MENLO PARK, Calif. -- Facebook has changed your email address. At least that's how many felt after a quiet but vast change in the way the company displays users' contact information.
Facebook replaced the email address users chose when they signed up and changed it to a facebook.com address. The Facebook email accounts allow users to communicate with outside email addresses via Facebook.
The changes were first pointed out by bloggers over the weekend and publicized by media outlets Monday, leading to gripes from users, usually on their Facebook pages.
An email message to Facebook representatives seeking an explanation was not immediately returned.
The company said in a statement in April that it was "updating addresses on Facebook to make them consistent across our site."
Users are free to restore their former email addresses.
