Yahoo! Messenger uses smart tags in instant messages—a feature that identifies phone numbers and email addresses and marks them so that you can act on them. When you see an underscored email address in an instant message, you can use the smart tag to invite the email owner to use Messenger.

In the IM window, click the underlined email address, then select Invite to Messenger from the menu.

The Add to Messenger List window opens.
Complete the Add to Messenger List window and send the invitation. (Remind me how.)
The Import feature, Invite to Join feature, and email smart tags provide ways to easily invite people to join you in using Messenger. Invite all your friends and connect the way you want, when you want.
