Add the tag {{rfc|xxx}} at the top of a talk page section, where "xxx" is the category abbreviation. The different category abbreviations that should be used with {{rfc}} are listed above in parenthesis. Multiple categories are separated by a vertical pipe. For example, {{rfc|xxx|yyy}}, where "xxx" is the first category and "yyy" is the second category.
