There's a number of ISP's available in the UK.
AOL is good for the technophobe net user, but once you start to want to use the net for other services rather than just surfing then dumping AOL is the best option.
It's slightly difficult to know which ISP are available in your area, but The Broadband Resource, located
HERE will help a great deal.
Just enter you Postcode and BT phone number and it will tell you want it available.
If you need any further advice feel free to ask.
