Articles such as compact discs are traded among a plurality of members who are registered in a common community. Each member has an account including a trading credit balance and a mailing address. A user interface is provided that allows a member to enter articles that the member owns and is willing to trade and articles that the member wants to own. The user interface also receives article trading instruction messages. An administration computer hosts the plurality of members and facilitates article trades among the members. The administration computer identifies matches between owned and wanted articles. For each identified match, an article trading instruction message is sent to the article owner requesting that the article owner mail the owned article to the mailing address of the member who wants to own the article. If the member sends the article, a trading credit is posted to the member's account and a trading debit and a monetary charge is posted to the member's account who will be receiving the article. Each traded article has the same trading credit. A priority algorithm is used to select the member who will receive the article if there is more than one member who wants an article that another member owns and is willing to trade. The priority algorithm is based in part on a member score that is a function of the relative value of the articles that a member owns and sends to another member compared to the relative value of the articles that the member wants and receives from another member, the relative value of the articles being determined by a demand for the article compared to a supply for the article among the members. A portion of the monetary charge is placed in a pool for distribution to the content creator of the article.
