y-notes is a set of lightweight applets and CGI scripts which enables a webmaster to specify points where the website's visitors may leave 'sticky notes'. The notes are kept on the server so that users can retrieve them at a later time and use them as a navigation aid. y-notes are particularly useful in large sites such as tutorials and reference manuals. They can also be used in web pages as a fairly uncomplicated way of gathering user feedback which requires no registration, logins, or passwords.
