(CNN) - Former Alaska Gov. Sarah Palin changed her Twitter account on Thursday to @SarahPalinUSA, abandoning her old username @AKGovSarahPalin.
There has been much speculation about when Palin would begin tweeting again. Since leaving office in July, Palin has been silent on Twitter and has primarily used Facebook to communicate with the public.
No tweets have yet been sent from her new Twitter account.
More than 135,000 people currently follow Palin on Twitter. Those who followed her official gubernatorial account do not have to re-subscribe to her new name. Twitter users who change their names maintain their followers.
UPDATE (Friday): A few hours after Palin changed her Twitter account name, she switched it back to @AKGovSarahPalin. @SarahPalinUSA is now a new separate account altogether. CNN e-mailed a Palin representative seeking comment, but has not yet heard back.
