All clubs come equipped with the Contacts feature.
Everyone who joins the club will automatically be listed on the Club Members page. Unlisted clubs also offer an Address Book feature. You must be over 18 to add or edit content in the Address Book. As the founder, you have the ability to add, edit, or delete contacts in the Address Book. If, as the founder, you add or edit a contact, your Yahoo ID will be posted next to that contact, reflecting the latest change.
