":Within the WP:WPMA it has been the convention to treat names of martial arts as common nouns (not capitalized), and not as proper nouns.  Where the word ""taekwondo"" is part of a proper name, such as an organization, it should be capitalized along with the rest of the name, such as Rhee Taekwon-Do (where it is also written according to the ""official"" name of the organization).  So the first line of that article might read: ""Rhee Taekwon-Do is a school of taekwondo.""
