Yahoo! Messenger is both software and a service designed to let you communicate instantly—and privately—with other Yahoo! members. When the Yahoo! Messenger software is running, you can send instant messages to any other Yahoo! user currently online, as well as receive up-to-the-minute stock prices,news headlines, sports scores, weather forecasts, and notification of any waiting Yahoo! Mail
You might not know it, but Yahoo! Messenger is one of the big players in instant messaging—right up there with AOL Instant Messenger, Windows Messenger (a.k.a. MSN Messenger), and ICQ. Like the other players, Yahoo! Messenger is a free service; all you have to do is download and install the Yahoo! Messengersoftware—which you do from the main Yahoo! Messenger page (messenger.yahoo.com).
After Yahoo! Messenger is running, you see the Yahoo! Messenger window
shown in Figure . When you click the Friends tab, all the members of your Friends List are displayed in the main Messenger window; friends online are displayed in bold.
To send an instant message, double-click any name in your Friends List. Whenthe Send Instant Message window appears, enter your message and click the Send button, or press the Enter key. (You can spice up your text with bold, italic, underline, or color, if you want.)
