From Connor Carney:
iChatWidget is a "widget" to display an iChat buddy list in the dashboard. Using AppleScript, it lists the handles of your available buddies. Clicking a name in the widget will open an iChat window where you can compose a message.
(An earlier version of iChatWidget was named "iChatter". The name has been changed to avoid confusion with a product of the same name by Ecamm Network.)
