A U.S. judge on Friday overruled a jury verdict and dismissed a case against a Missouri woman convicted last November in a cyberbullying case that led to a teenager's death.

A little-noticed bill re-introduced in Congress last month would make the use of popular electronic communications a felony if "the intent is to coerce, intimidate, harass, or cause substantial emotional distress to a person."

Seventeen social-networking Web sites including household names such as Facebook, Bebo and MySpace have signed a voluntary code of practice designed to stamp out online bullying of children and to inform kids how to protect their personal information, the European Commission said Tuesday.
