Typing is becoming a part of a person’s literacy indicator today. If you cannot touch-type, all of your computer-based tasks will be more difficult not to mention slower.
www.sense-lang.org is a very good free on-line typing tutor. It has a decent set of standalone typing tutorials. It also has a classroom learning mode for teachers to set up and use it with their students in a controlled mode. It also has lessons for seniors.
The site is very powerful in terms of typing tutorials but a bit awkwardly designed in terms of web aesthetics. Nevertheless it is very useful and free.
