Why are some of the pages scrunched together and capitalized LikeThis?
The original wiki standard is to treat anything scrunched together and capitalized LikeThis (sometimes called CamelCase) automatically as a link. This linking style was originally used by Wikipedia, but we now use free links. If you come across an old CamelCase link or article, you should rename (move) it to the new style, so that the CamelCase name redirects to the new title.
