y-notes is a simple system which allows you to specify spots in your web pages to which your website's visitors will be able to stick notes. For the the web user, y-notes provide a convenient way to add annotations to a web site without having to go into the messy business of managing a large set of bookmarks. Also, the notes are kept at the server so that users can retrieve them at a later time and use them as a navigation aid. For the site maintainer, y-notes provides an easy and automatic way of gathering user feedback and improving the site design. The main component of y-notes is a tiny Java(tm) applet. Notes are stored on database managed through a CGI interface written in Perl.
