I have a suggestion for the homepage, how about you have a tick-off button that say's keep me logged in? That would be very useful, seeing as I go on www.pcspecialist.co.uk quite a lot and I always get logged out.
I think this has been asked for before, and I think they don't do it cos it is a security risk since if you're logged in to the main site you can get to all your order,name,address details and such.
Note: I could be wrong, it was a while back and my memory isn't that great at the best of times.
I'd quite like this to be implemented, if it was, it would be a lot easier, but maybe put a longer time of when to automatically log off like maybe 30 mins if you haven't been on the website?
