  == English spelling ==  Hi there.  Be aware that that UK-style spelling in articles is explicitly permitted by the Wikipedia:manual 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 UK-style spelling if a) the article is inconsistent, or b) it's an article on a topic more closely related to the United States (or another country where a different variant of English is used).
