Share a status update (e.g. "Hard at work!") for all accounts by clicking "Share a messaage..." or any existing status message:

By default, Trillian is set to update your status message on All IM Networks. If you would also like to also update your social network status you can click the selection to the right of "Set Status for" and check/uncheck your selections:

Global Away Status
When setting yourself as Away, Trillian will automatically change your status message to show what time you went away. It pre-fills the status message box so that you can edit it yourself:

Simply start typing to replace it with a custom away message.

You may edit saved Status Messages by clicking the "Edit status messages..." button:

Saved Status Messages allow you to configure
re-usable states with finer control.

Set each service's state (Online, Away, Invisible, etc).
Quickly change to a saved status message from the top of your
