Thank you
I will have a proper read of that, however based on the couple of links I read so far (Ryanair's own, plus the Tele), I am wondering how clear a comparison there is between terms and conditions governing a financial transaction (where a contractual relationship has been deliberately and verifiably created in a way recognisable in common law) and terms and conditions that seek to control access to something that is entirely in the public domain without any financial consideration being due.
