English spelling   Hi there  Be aware that that UKstyle spelling in articles is explicitly permitted by the Wikipediamanual of style  Spelling should be consistent throughout an article and if the topic is one particularly associated with one type of English the article should reflect that style for instance articles about Australians should use Australian English  So you should only change correct UKstyle spelling if a the article is inconsistent or b its an article on a topic more closely related to the United States or another country where a different variant of English is used
