A method for templates for implementing instant message themes is provided. For example, the user selects between a "to-do" theme, an "invite" theme, a "postcard" theme, a "reminder" theme, etc. If the user selects the "to-do" theme, the to-do template may prompt the user to input a description of the task to be performed and a due date/time. An instant message is sent to a recipient who is to perform the task. The recipient's instant message application displays a to-do in a themed IM window. The themed IM window may have special features that are related to the interactions for the to-do theme. For example, the themed IM window can have a "completed indicator" for the recipient to send a completion notice to the sender. Alternatively, the themed IM window could have a button to perform the task. In response to performing the task, the to-do theme could automatically send a completion notice.
