The scenario is you are without Internet connectivity anywhere. You have found either an open wireless access pointed or perhaps you're staying in a hotel which permits rented Internet via services like
Spectrum Interactive (previously known as UKExplorer). You make the connection, whether its physically connecting the Ethernet cables, or instructing you're wireless adapter to lock onto the radio signal. You are prompted with some sort of authorisation page when you open a browser. You don't have access to it, so what do you do?
