GlobalConfig Name	Description
AllowAffiliateFiltering	This setting determines whether Affiliates mapped to one site also function on others in the same instance. If this is set to false, AffiliateIDs tied to other stores will be ignored on stores they aren't mapped to.
AllowCouponFiltering	This setting determines whether coupons mapped to one site also function on others in the same instance. If this is set to false, customers will receive an 'Invalid Coupon' message if they try to use a coupon on a store it is not mapped to. See this page for more details.
AllowCustomerDuplicateEMailAddresses	This setting determines whether customers' email addresses must be unique, or can be re-used. Allowing duplicate email addresses can cause confusion between purchases, and make accounting more complicated. We almost always recommend that this be set to false, unless 'AllowCustomerFiltering' (see below) is set to true.
AllowCustomerFiltering	If this is set to false (recommended), a customer that registers on one of your MultiStore sites also becomes registered on all other stores in that instance. Their login, addresses, order history, etc will be shared across all of the stores. If set to true, the customer must register independently on every store. Setting this to true requires that 'AllowCustomerDuplicateEmailAddresses' be true as well.
AllowEntityFiltering	If this is set to true, entities (categories, manufacturers, departments, etc) will only show up on the stores that they are mapped to. See this page for more details.
AllowGiftCardFiltering	This setting determines whether gift cards mapped to one site also function on others in the same instance. If this is set to false, customers will receive an error message if they try to use a gift card on a store it is not mapped to. See this page for more details.
AllowNewsFiltering	If this is set to true, news articles will only show up on the stores that they are mapped to. See this page for more details.
AllowOrderOptionFiltering	If this is set to true, order options will only show up on the stores that they are mapped to. See this page for more details.
AllowProductFiltering	If this is set to true, products will only show up on the stores that they are mapped to. See this page for more details.
AllowRatingFiltering	If this is set to true, customer product ratings will only appear on the store they were created on, even if the product is mapped to multiple stores.
AllowShippingFiltering	If this is set to true, shipping methods will only appear on the stores they are mapped to. If this is set to true, make sure that every store has at least one shipping method mapped to it or customers will be unable to check out on stores without a mapped shipping method!
AllowShoppingcartFiltering	If this is set to false, customers can add products from multiple stores to a single cart, and check out on any of those stores. Note that 'AllowCustomerFiltering' must also be set to false for this to function.
AllowTemplateSwitchingByLocale	If this setting is enabled, the stores in this install will be able to switch to another skin when a customer chooses a locale.
AllowTopicFiltering	If this is set to true, topics will only show up on the stores that they are mapped to. See this page for more details.
