A portal switch is provided that controls participation of merchants in on-line aggregators, such as portals, used for buying and selling goods and services. Merchants may enable or disable participation in an aggregator site by turning on or off software settings. When participation is enabled, the merchant's site makes its catalog entries and merchant profile available to the aggregator. By enabling or disabling the switch, the merchant actively expresses a willingness to participate in (or, conversely, a desire to be excluded from) the aggregator. |
