Abstract: A system and method are described herein for enabling end-users of mobile terminals to exchange messages that are associated with a specific geographical location. In one embodiment, a first end-user can use their mobile terminal to submit a message (text, voice, video . . . ) about a specific piece of art located in a museum. Then, a second end-user can use their mobile terminal to retrieve the message (which was previously provided by the first end-user) that is associated with the specific piece of art while they are located in the museum.
