Methods, systems, and program code for implementing instant messaging systems having a feature permitting modification/deletion/substitution of previously transmitted messages in an instant messaging session are provided. In an example, a first computer is operable to interpret a user action as a request to modify at least one previous instant message, to capture a selection to modify of the at least one previous instant message, query the user for the modification to be applied, and formulate content that indicates the modification for transmission to a server. The server is operable to receive the content, detect the modification in the content and form an update message for transmission to each client participating in the instant messaging session. Each client in the instant messaging session may be operable to receive, and use the update message for altering a display of the at least one previous instant message according to the modifications indicated.
