Nothing! At the moment, listing is free of charge, there is a chance in the future we may ask for a small donation towards the site (still in consideration) to help pay for the up-keep, however you will not be 'required' to do this, you can choose simply to 'opt out' of your listing. We will email you with more information 'as and when' or 'if' this is going to happen.
Whats the catch then? - All we ask for in exchange for your free listing is that you publicise our website to the best of your ability to your colleagues and our online shop to your students as the small income we gain from these sales helps pay for the existence of the website.
