Systems and techniques for tailoring the storage of information. In one implementation, a computer program product is operable to cause data processing apparatus to create a framework of elements to present a user with a presentation of options for tailoring an object, receive user input for tailoring the object in response to the presentation of options, define the tailored object to include the first field and the second field, associate an identifier of the first participant with the first field to indicate that the first participant is to be excluded from a first activity performed with the first field, and associate an identifier of the second participant with the second field to indicate that the second participant is to be excluded from a second activity performed with the second field. The received user input can identify a first field to be included in the tailored object, a second field to be included in the tailored object, a first participant, and a second participant. The computer program product can be tangibly embodied in an information carrier.
