Richard Minsky, an artist and publisher who operates in Second Life, is suing an avatar, which is a representation of a real person, along with two directors of Linden Lab, owner of the virtual world, over use of the word "SLART," the Daily Telegraph reported Tueday.

In a 25-page complaint to the U.S. District Court of New York on March 16, 2008, Minsky's attorney, an avatar called Juris Amat, sent Vezina a "cease and desist" order that he failed to respond to, the newspaper said.
