`
`Chapt e『 14: Instant Messaging
`
`Yahoo, the web portal at www.yahoo.com, has its own instant messaging service,
`called Yahoo Messenger. (Yahoo! and Yahoo! Messenger actually include exclamation
`points in their names, but we omit these for readability.) Yahoo Messenger is very
`popular among people who use出emany Yahoo functions such as e-mail, discussion
`boards, shopping services, maps, st促 kquotes, and more. Yahoo Messenger is a
`vailable for Windows 95/98, NT, 2000, ME, and XP; PowerPC Mac 8.5 or higher;
`several versions of RedHat and FreeBSD Linux; Java; Palm handhelds; Windows CE;
`and web-enabled telephones. You can learn about and download Yahoo Messenger
`at the messenger.yahoo.com web site. (See Chapter 34 for information about how to
`download and install programs from the Web.)
`Yahoo continually enhances Yahoo Messenger, and in each operating environment
`its use may be slightly different.官leinstructions provided in this book are for using
`Yahoo Messenger version 5.0 on Windows XP, but users of other versions should have
`no difficulty adap由lgthese directions for use with their configurations.
`
`Getting Started with Yahoo Messenger
`After you’ve installed Yahoo Messenger, the Login window opens:

`them each time you log onto Messenger. If you also choose to Automatically Login,
`you will completely bypass the Login window when you start Messenger and can
`thereby log into Messenger very quickly.官1ethird option is to Login Under Invisible
`Mode.百usprivacy function prevents other Yahoo Messenger users from knowing
`you are logged in.
`Yahoo Messenger is designed to run whenever your computer is n江ming.This
`enables the program to alert you when one of your friends comes online or when
`someone wants to contact you. When Yahoo Messenger is r山 ming,you see a red Y
`behind a yellow smiley in血esystem tray. Double-click the位ayicon to open the
`Yahoo Messenger window.

`
`Conferencing Is More Than Talking and Seeing
`Mostconfe四 ncingsoftware lets you do more血anjust talk and exchange video. Software
`conferencing applications can simulate a business meeting where all participants are
`gathered in one conference room. In Table 16・l,many of the features seem like they are
`p叫ledright out of the business world (such as wri也市 ona whiteboard, for example).
`Conferencing features may be named after actions that take place in business, but
`you can use conferencing software in your personal life, too. To show how you can
`adapt conferencing software from a business conference venue to a different set肱lg,
`suppose, for example, that you are p加 minga family reunion. Table 16・2showssome

`This is used when you have rr同 nypeople in the

`talk to and see o吋yone person at a time, so using the

`with a lot of people.
`
`File transfer
`
`This sends a copy of a file to one or all meeting

`
`Sharing an application This opens an application and lets others see the
