A server has a processor and a memory storing a message thread module with instructions executed by the processor to maintain a message thread between users of client devices. The message thread module serves a message thread with a new text entry to a client device in response to a request for the message thread from a user. Message thread state change is collected from the client device, where the message thread state change represents an indication to automatically delete the new text entry of the message thread after the duration of a transitory display period on the client device unless an indication of a gesture applied to a display screen presenting the new text entry of the message thread is received from the client device during the transitory display period. The message thread state change is queued at the server along with additional message thread state changes associated with the collecting operation performed for additional users associated with the message thread. The message thread is revised based upon the message thread state change and the additional message thread state changes to form shared message thread state. The shared message thread state is stored. The shared message thread state is supplied in response to a request for the message thread from a user.
