I've never been a great fan of GMail and perhaps that's because I've never really put the time into learning how to use it properly.
Anyway, this is a free course, but students do need to register. It's a good way though to get students learning something in English and helping them to improve their IT skills at the same time. Most of ALISON's courses are quite media rich with sound and interaction, so this could be a motivating language learning experience too.
