The Aims:

Spoken - to improve your discussion abilities
When you are working with other students on web pages, you will need to
make your ideas clear through giving opinions, agreeing and disagreeing.
Being able to do these things is very important in English.

Written - to improve your editing abilities
Because what you write could be seen by quite a large audience on the
Internet, it is important to avoid mistakes, whether grammar, spelling
or style.

Technical - to improve and practice computing skills
Learning English at the same time as doing something else, like practicing computing, is always positive.  More and more kinds of jobs need computing skills and thet often also involve English.
