Abstract: Methods, systems, apparatus, including computer programs encoded on a computer storage medium, for providing a publisher with a privacy control UI that enables the publisher to assign one privacy wall to each domain-purpose pair; determining that the publisher has created an additional privacy wall for a specific domain-purpose pair that has an existing privacy wall; in response to determining, restricting the specific domain-purpose pair to a single active privacy wall, including: in response to creation of the additional privacy wall: enabling only one of the existing privacy wall and the additional privacy wall to be in an active state; maintaining any privacy wall that is not in the active state in an inactive state; detecting a transition of a specific privacy wall from the inactive state to the active state; in response to detecting, transitioning a different privacy wall from the active state to the inactive state.

Abstract: A method of placing an order for a custom stamp, including purchasing a standard stamp mount where each stamp mount has associated with it a separate discreet identifier. Under control of a client system, information for ordering the custom stamp is displayed and a request to order the custom stamp is sent using the separate discreet identifier to a server system. Under control of the server system, the request is received and additional information previously stored and identified by the identifier is retrieved. Under control of the client system, a custom impression is designed and previewed. Under control of an ordering component of the server system, the request is received and identifying information to identify a purchaser is requested. An order to produce the custom impression for the purchaser is generated.
