Userspace means the Uncyclopedia pages that "belong" to you. In your userspace, you can experiment with things that would not fit in the main encyclopedia, and other Uncyclopedians should mostly only contribute with your invitation. There is an infinite number of names for pages in Uncyclopedia. As you are , any page whose name begins with "User:/" is a page in your userspace. After the slash, you can type whatever name you want to give to the page. If you are writing an article for the main encyclopedia, you'll type after the slash its eventual name in the encyclopedia.
