Make first-user experience smoother.

We should make it very obvious to a user what the tool is and how to use it when they first see it. A couple of ideas:

• Our landing page should state what the tool does ("Easily create and collaborate on editing Wikipedia articles!" or something).
• It should allow easily exploring existing worklists, whereas right now this is somewhat hidden under a dropdown in the header of the page. I could see us having something like "Browse some worklists or log in to create or collaborate in one!" in the landing page, where the parts in bold are links to the corresponding actions. We can't really rely on people finding these actions in the header on a first visit IMHO, though the header should remain there to access these functionalities past the landing page.
• The Create Worklist should be a lot more prominent. I'm fine with having it in the header, but it should be one of the first things a user sees after logging in.
• The Create Worklist page should offer some text explaining the individual fields, or at least placeholder values for the input elements that give an example of what they're meant to be.

How about this for the text of the landing page:

Create a easy-to-share worklist of Wikipedia articles and collaborate in real time to improve them! You can import worklists from PetScan queries or add individual articles manually, then share a link to the worklist to start your own edit-a-thon.

and then the buttons Browse worklists and Log In to create a worklist.
