Guestbook — 1990s Personal Website Guestbooks and AOL Chat Rooms

A guestbook was a common feature on personal and fan-run websites in the late 1990s. Visitors could leave a short message with a screen name and date. Guestbooks served as lightweight community interaction before blogs or social media existed. In Doors 98, the guestbook is reimagined as a live chat-style interface inspired by AOL chat rooms and ICQ.
