Guestbook

A guestbook is a paper or electronic means for a visitor to acknowledge a visit to a site, physical or web-based, and leave details such as their name, postal or electronic address, and any comments. Such paper-based ledgers or books are traditional in churches, at weddings, funerals, B&Bs, museums, schools, institutions and other private facilities open to the public. Some private homes keep visitors' books. More at Wikipedia
