Creating a new page is simple. All you have to do is first go to an existing page (ex: wikiuniverse.wetpaint.com/page/Home+Page) and as you see, the name of the page will be in the URL title. (ex: ...com/page/Home+Page)
So therefore, to create a page take out the name of the page you are on (on the URL) and make it into your own page name. Make sure to put a '+' in between the words to make a space! Like this:

wikiuniverse.wetpaint.com/page/Home+Page
| Change to... |

wikiuniverse.wetpaint.com/page/Video+Games --(or)-- wikiuniverse.wetpaint.com/page/My+Page
