Here's how to set up Jabber for Messages. In Messages, click the Messages menu at the top of the screen and click Add Jabber Account. Enter your email address and password and click the Sign In button. Messages will authorize your account details and add Jabber. To manage accounts, open the Preferences menu by clicking it under the Messages heading or pressing Command/Ctrl-comma on your keyboard. On the General tab of Preferences, click the Default IM Application pull-down menu to decide which service to use as your default. Whichever service you choose will load when you first open Messages.
