How do I activate an 'offer code'?
If you are a new user, you can activate an offer code by clicking Register Now, then filling out the form. Enter the offer code in the Offer Code field, then click Submit to register and activate the code, all at once.
If you have already registered as a Cambridge Journals Online user, log in in the usual way then go to 'Change Registration Details' in the 'My CJO Links' menu. Enter the offer code in the Offer Code field, then click Submit to activate it.
If you have more than one code to activate, just click the 'Change Registration Details' link after you've activated your first code, then enter your next offer code in the Offer Code field and click Submit to activate it. You can repeat this process for as many offer codes as you need to activate.
