WASHINGTON (AP) — Trying to find Michelle Obama on Twitter? Try tweeting her at (at)FLOTUS, which is Washington shorthand for “first lady of the United States.”

Mrs. Obama’s office unveiled her new Twitter identity on Thursday, largely to replace a previous Twitter account under the handle of (at)Michelle Obama. That account was launched a year ago and run by President Barack Obama‘s re-election team. It will now be managed by the Democratic National Committee.

The site’s initial tweet promised updates and pictures. Tweets by the first lady herself will be signed “-mo.”

Followers also were asked to re-tweet that initial message to wish Mrs. Obama a happy birthday. She turned 49 on Thursday.
