The Skype Email Toolbar: Import and call Outlook and Thunderbird contacts from within Skype

Do you use Skype as your VoIP client?

The Skype Email Toolbar makes it easy to port your contacts directly into the application from Outlook, Outlook Express and Thunderbird. The toolbar also allows a user to call Skype contacts and phone numbers listed within email, see when contacts come online and add a Skype button to your email signature.

Make sure to do your due diligence on VoIP security first, however, before you start Skyping your coworkers, clients, friends and relatives.
