Linux Format is a monthly UK Linux journal which is delivered worldwide. It includes tutorials, a Reader Round Table and a distro DVD. The website hosts a wide range of forums for user discussions. The magazine also produces 'specials' for beginners introducing various distros or describing common programs like OpenOffice.
