Cookies are small text files that most web sites use (thousands of sites are currently using them) to recognize a repeat visitor to its site. Cookies are not programs that come onto a user's system and damage files. They are used simply to determine what users are interested in, without forcing users to log in and register each time they visit the site. We believe that cookies enhance the Web experience by increasing the level of relevant content on the Web, thereby allowing us to respond to the needs of our users. If you do not want cookies to be saved onto your machine, you can set your browser to deny it; however, users should note that certain features on the site (e.g., customized delivery of information) may not be available to you.
