[Name of Field] Category [Description of Feed] Some RSS directories allow users to search for feed items that they are interested in, by category. You can create your own categories, but typically you will want to use a more standard predefined category. DMOZ is probably the most popular category system. Example DMOZ category: Computers/Internet/On_the_Web/Weblogs/Tools If a predefined category is used (i.e. from DMOZ), you should set the category domain field to point to the category system's website. Example DMOZ domain: http://www.dmoz.org Both the Category and Domain fields are optional. [Required / Optional]
