Each user can specify at least one barterable item in a wish list and at least one barterable item in a trade list. Within a given community, the system periodically compares the wish lists and trade lists only of users within the community in order to identify a trade match. When a match is identified, an e-mail message is sent to users advising of the trade match. The system also receives confirmation from the users accepting or rejecting the trade match. ## Claims ### Claim 1 An electronic bartering method, comprising: registering a plurality of persons as users of an electronic bartering system; associating each user with at least one community and enabling users to create their own communities; enabling each user to specify at least one barterable item in a wish list and at least one barterable item in a trade list; within a given community, periodically comparing the wish lists and trade lists only of users within the community in order to identify a trade match; sending an e-mail message to users advising of the trade match; and receiving confirmation from the users accepting or rejecting the trade match. ### Claim 2 (depends on 1) A method according to claim 1, wherein a trade match is identified when an item on a first user's wish list appears on a second user's trade list and another item on the second user's wish list appears on the first user's trade list. ### Claim 3 (depends on 2) A method according to claim 2, wherein: each community is designated as either a private or a public community;
