Britain's royal family has extended its kingdom further into cyberspace and joined Twitter — but don't expect Her Majesty to tweet.

Buckingham Palace, which already has a significant online presence, said Friday that it has set up a Twitter account to alert royal watchers to what's happening with the family.

But that won't result in any re-tweets or trending topics from Queen Elizabeth II or Prince Charles. A palace spokeswoman says the account won't be used to air personal opinions.

The queen launched Buckingham Palace's Web site in 1997. She also has her own YouTube channel.
