  • Under "Password", enter your password.
  • Under "Server", enter
  • Click "Login".
  • That's it. To add a new contact to your roster, from the menu select "Contacts" => "Add Contact", and type in the contact's Jabber ID e.g. . To join a conference, select the "Conferences" tab, then click on the icon that looks like two small balloons (the ToolTip? reads "Join a Conference Room"). Spark will show you a list of public conferences, and you can bookmark conferences you join frequently. To join a conference, simply double click on it. To start a private conference, select "Actions" => "Start a Conference" and enter the Jabber IDs of the users you wish to invite to the conference. (Under "Room" you can change the name of the conference to something more meaningful; by default it's your name with a random string appended.)
