Maybe you've seen some of the new cool web sites that automatically let you import people from your Outlook, Yahoo, Gmail, or other contact lists. That way your users don't have to remember or type in their friend's email addresses ... they just pick from an imported list.

Well I noticed that Plaxo has an Address Book Widget you can embed in your site that allows your site visitors to import contacts from Yahoo, etc. It would probably take you under an hour to implement on your site.

FYI, the widget is free, but it contains a link to Plaxo.com.
