Pidgin (new name for well-known game) is a multi-protocol instant messaging client that lets you use all your IM accounts at once. It does not matter if you use AIM, Bonjour, Gadu-Gadu, Google Talk, Groupwise, IRC, MSN, MySpaceIM, QQ, SILC, SIMPLE, Sametime, XMPP, Yahoo! or Zephyr. Pidgin does not require you to run all your instant messenger programs, because you only have all your contacts in one program (any IM network they will use).
It also includes all the key features of each IM program and adds more such as spell checker for different languages. If you like instant messages, and you have contact with any instant messaging network, you'll find the pydin really useful and comfortable.
