This invention relates to instant messages. More particularly, the invention relates to the delivery of revisions of instant messages that have already been previously delivered from a sender's instant message client to at least one recipient's instant message client during an instant messaging communication. Typically, revisions are made by the original sender of the instant message with the intent to correct misspellings or mistakes. Also, typically, an instant message client displays a revised instant message differently from an unrevised one with the purpose to bring revisions to the attention of the user, and so not to be mistaken for original content. In addition, the instant message client may mark or change the display of the original message that has been superseded by the revised message.
