Plaxo

With so many ways to communicate it is difficult to keep on top of all your contacts, especially with people moving house and changing e-mail address and telephone numbers so frequently. Losing touch will be a thing of the past if you sign up to Plaxo. (www.plaxo.com)

This is basically a contacts management service which connects you with your friends and family and helps you all keep up to date with each others' changes.

There is so much more to this site, have a good explore of the features. I do want to draw your attention to the option to link up your account with other sites that you subscribe to - such as YouTube, , your blog, or any number of photo sharing and social networking destinations.
