If you're talking about user pages (e.g. User:Neshomeh), you get that when you sign up for an account on Wikia.
When an article has something at the front with a colon like that, it's called a namespace. User pages go in the User namespace, and the only way to get that is to make an account. Images (e.g. File:Imagename.gif) are in the File namespace, which you only get when you upload an image. You can get other namespaces by naming them that way when you make the page (e.g. FAQ:For Other People).
I'm guessing that isn't what you're talking about, though. For editing help, I suggest starting with the Help:Editing page (which, as you may have noticed now, is in the Help namespace).
