Pidgin is a chat program which lets you log in to accounts on multiple chat networks simultaneously. This means that you can be chatting with friends on MSN, talking to a friend on Google Talk, and sitting in a Yahoo chat room all at the same time.
Pidgin runs on Windows, Linux, and other UNIX operating systems.
Pidgin is compatible with the following chat networks out of the box: AIM, ICQ, Google Talk, Jabber/XMPP, MSN Messenger, Yahoo!, Bonjour, Gadu-Gadu, IRC, Novell GroupWise Messenger, QQ, Lotus Sametime, SILC, SIMPLE, MySpaceIM, and Zephyr. It can support many more with plugins.
Pidgin supports many features of these chat networks, such as file transfers, away messages, buddy icons, custom smilies, and typing notifications. Numerous plugins also extend Pidgin's functionality above and beyond the standard features.
Pidgin integrates with the system tray on Windows.
Sean: 2.2.0 contains the results of several major Google Summer
of Code branches bringing some new, extraordinary features. We
have a new protocol, MySpaceIM, a bunch of new features for an
existing protocol, XMPP, and nifty new certificate management
to make sure your IM server is who it says it is.
Ka-Hing: A number of you noticed crashes when dragging windows
around when certain options are enabled. Well, that was my fault,
and Sadrul fixed it. So Props to him and poos to me. I haven't
done much for this release, but the next one should contain
something that I helped work on. Hint: students are cheap slave
Kevin: I haven't really been coding much in Pidgin, and this
release is no exception, but I will be working on getting our
wonderful web site to be a little more functional by next
release. I promise!
