Yahoo! Messenger is a popular
advertisement-supported instant messaging client and associated protocol
provided by Yahoo!, that allows you to see when friends come online and to send
them instant messages. It also can alert you to new e-mail in your Yahoo Mail
or Yahoo Personals accounts, or when you have upcoming events recorded in your
Yahoo Calendar.
Yahoo Messenger offers firewall support, a standby mode that
minimizes the program until an Internet connection is made, the ability to save
and print your conversations, and a tabbed interface that provides quick access
to your favorite stocks, news, and sports scores.
Yahoo!
Messenger is provided free of charge and can be downloaded and used with a
generic "Yahoo! ID" which also allows access to other Yahoo!
services, such as Yahoo! Mail, where users can be automatically notified when
they receive new email.
