creates a beautiful show/hide index. used for many purposes like business directory/profession directory and more. easy to ust. see screenshots.
that is probably because you didn't added any posts under "index" so the categories are empty.
under "location" you need to write the address. like: 903 E colorado, urbana, illinois.
that plugin has only one CSS file, just go in and change what you want.
you need to change the Permalink Settings for your site. go to "settings"--->Permalink Settings-->set it to "Post name"
