This is the Userpage policy. All users must follow these guidelines for their userpage and subpages.
Backgrounds
Backgrounds on userpages should have <span class="userBGImage"> and </span> on the left and right of the background code respectively.
Page elements
Embedded players and YouTube videos are allowed to autoplay, but must not be hidden from view. A pause button must be present at the top of the page.
Text
Users have free reign to post what they would like on their userpage so long as it is not in violation of any other policies. Everybody has opinions, but if these opinions are deemed offensive to others, the userpage in question may be edited, locked, or deleted without warning.
