At the top of every page there is now a link to a large range of social bookmarking websites.
These sites allow you to store, tag and share links across the internet. You can access your links from any computer you happen to be using. You can share these links both with friends and people with similar interests (or keep them private!).
So, if you come across a page that you find interesting and want to save for future reference, simply click on the link to add to your list.
All of these sites are free to use but do require you to register. Once you have registered you can begin bookmarking.
Each of the sites works slightly differently so use the sample help links below to find out which service best suits your needs.
You can find out more about social bookmarking on Wikipedia.
More details can be found below for some of these services:
