 Essential Formatting III: The User Page
The user page is your own little slice of DandWiki. Some people choose to have plain user pages, some people like to list all of the material they've contributed, and others like to have a pretty page. Which will you be? Honestly, it doesn't matter what you put on your user page (as long as it's appropriate). Check here <when I get to it> for a list of wiki codes you can include on your user page. It should be noted that if you want to display something, it should be on your user page, not your talk page. Your talk page should be left for conversations with other contributors.
