I changed your revision to the Krav Maga page. You can find webpages that state Krav Maga incorporates many martial arts that aren't accurate. Unless you can find a source that states who introduced the art, when the art was introduced, and where the person learned the art from then please don't edit articles. Also, if you are going to edit an article make sure to edit it in it's entirety; you changed the principle arts in the first few lines, but didn't change the rest of the article to comply. Showing that you didn't actually read the whole article or the links supporting the previous claims.
