I wanna make a plain sitemap just like this site.. http://www.funadvice.com/sitemap what kind of program should I use? thanks
An HTML editor. If you're looking for a solution for an existing content management system, there are plenty out there if you do a little searching around. For example, there's a Wordpress plugin that accomplishes what you're wanting.
I don't have to do everything for you, right? You know exactly what you want. If you're using Joomla or Drupal, search "Joomla/Drupal sitemap plugin/extension". If you're using static HTML pages, try searching for software that will generate it, or do it by hand.
