To make logging on easier you can choose to save your user ID on your computer so you won't need to enter it each time you come back to the site.
However, if you are using a shared computer we would not recommend using the Remember me facility. To stop your ID being remembered simply un-tick the selection box the next time you log on.
We remember your user ID with an 'encrypted cookie' stored on your PC. This holds your user ID ready for your next visit. For further information on cookies please refer to the following website: www.aboutcookies.org.
