Yahoo! Messenger you can send instant messages, call computers, call a phone number, send a mobile message, or sign in to Yahoo! Mail.
You can edit your current status or change your picture. It's also possible to create your own avatar, which is displayed next to your name in your friends' contact list. Sharing your webcam or seeing other people who enable their webcam is easy. If you don't want anyone to see when you are online you should log on using the "Invisible" status. Nobody, except the people you select, would notice you are around. Messages are sent to your friends regardless of their online/offline status. Depending on your network configuration, you should also be able to use this instant messenger for sending files.
During instant messages you have the possibility to customize fonts, send emoticons and audibles, and select IMVironments. Everything is provided for you to have a great time while chatting with your friends. The Inside Yahoo! window provides quick links to news, finance, personals, movies, horoscopes, etc. You also get notifications of new emails and voice messages in this window. If you don't like this feature, you can turn it off from the program's preferences.
In version 8, the "Content Tabs" in the "Preferences" window has been removed. Now "Yahoo! Plug-ins" are available. So far you can install about 15 plug-ins like Music LAUNCHcast, Answers, 360, eBay, iTunes, Amazon.com, Finance, Calendar, Weather, and others. It's easy to stay up to date with new music, movies, sports results, and other stuff that may be of interest to you.
