A first user, second user, and third user are registered. Names of a first, second, and third item are stored a website for the first, second, and third users. The items can be tangible items or intangible items. The first user requests the second item. A first credit is removed from the first user and a second credit is stored for the second user when the first user receives the second item. The second user requests the third item. The second credit is removed from the second user and a third credit is stored for the third user when the second user receives the third item. The first credit, the second credit, and the third credit each represents a right to request a future swappable intangible item for the equivalent value of at least one previously swapped intangible item. |

1. A system for managing swaps of intangible items, comprising:
a server computer that is connected to an electronic database, and communicates with users through a network connection, wherein the server computer registers a first user in the electronic database, receives a first name of a first intangible item to list from a first user device through the network connection, stores the first name in the electronic database, and lists the first name on a web site of the server computer, wherein the server computer registers a second user in the electronic database, receives a second name of a second intangible item to list from a second user device through the network connection, stores the second name in the electronic database, and lists the second name on the web site of the server computer, wherein the server computer registers a third user in the electronic database, receives a third name of a third intangible item to list from a third user device through the network connection, stores the third name in the electronic database, and lists the third name on the web site of the server computer, wherein the server computer receives a first request through the network connection from the first user device for the second intangible item that begins a first transaction, removes a first credit from the first user in the electronic database that was stored for the first user during a previous transaction, sends a first message through the network connection to the second user device requesting that the second intangible item be provided to the first user, receives a second message through the network connection confirming receipt of the second intangible item, and stores a second credit for the second user in the electronic database to complete the first transaction, wherein the server computer receives a second request through the network connection from the second user device for the third intangible item that begins a second transaction, removes the second credit from the second user in the electronic database, sends a third message through the network connection to the third user device requesting that the third intangible item be provided to the second user, receives a fourth message through the network connection confirming receipt of the third intangible item, and stores a third credit for the third user in the electronic database to complete the second transaction, and wherein the server computer uses the first credit, the second credit, and the third credit to manage a swap of the second intangible item and the third intangible item among the first user, the second user, and the third user, wherein the first credit, the second credit, and the third credit each represents a right to request a future swappable intangible item for the equivalent value of at least one previously swapped intangible item. |
