Using this platform is free of charge. It will remain so in spite of the costs of hosting and maintenance during the
testing period. Then a small sum may be charged to the school or university wishing to use it, depending on the licence they will choose, in case more costly hosting facilities are
required.
Teachers wishing to get an access code are kindly requested to indicate what sort of licence they need when
they open an account. The number of users (teachers and students) will be limited depending on the licence.
