My son has downloaded eMule. What exactly does it do? Is it safe and legal? John Le Vay
eMule is a popular file-sharing client: see http://en.wikipedia.org/wiki/EMule for details. It uses a credit system that forces people to share (upload) files, not just download them. It is legal to use eMule, but it can be used to share copyright music, TV shows and movies, which isn't legal. Uploaders are more likely to be sued than downloaders, and some eMule/eDonkey users have been sued, but millions of people still use it.
