Q.
How do I use MSN, Yahoo, Jabber, IRC, Gadu-Gadu(GG), Napster, or Zephyr? A.
First load the plugin. Protocol plugins come with Gaim, so just go to the Plugins dialog (Tools->Plugins, or the Plugins button on the start screen) and then click "Load." The protocol plugins are named libprotocol.so, so MSN for instance is provided by libmsn.so, and Gadu-Gadu is provided by libgg.so.
After you have loaded the appropriate plugin, use the Account Editor (Tools->Accounts, or the Accounts button on the start screen) to add the account.
In 0.60 and latter, loading the plugin is not necessary, as protocols are automatically loaded as needed.
