When the applet is loaded, a window will open up and you will be asked to log in. On the map, simply click where you are from. You may also enter an optional comment.
Logging in may take a while, depending on the line speed.
When you are logged in, the Window will change. At the top of the frame, there will be a list of the users that are currently using the system. Double click on a user to get more information about that user. You may select any number of them and click on one of the Commlets below this list to start a new channel.
The list below the Commlet icons shows the channels that are currently open. To join a channel, select it and click on the "Join" button. You may also double click on a channel to see who is on it. If you select a channel you are on, you may invite others to that channel. Simply select them in the user list at the top of the Window and click on the "Invite" button under the channel list.
To log out, select "Quit" under the "File" menu.
