Skins can be used to change how the wiki is displayed. Users can change which skin to use at Special:Preferences, under My Info > Appearance > Layout. The default skin is Wikia (also known as Oasis), but you can try a page out in Monobook (classic Wiki styling) by adding ?useskin=monobook to the end of the web address (e.g. matrix.wikia.com/wiki/Matrix_Wiki:Skins?useskin=monobook). This page lists the pages which can be used to modify the skins available on My English Wiki as well as images used by these skins.
