Voting confusion

Hello!
I'm really impressed with 4.7 - it's so easy to work with!
I'm trying to do something relatively simple, but i've got a bit lost. I have voting actions, voting api, and simple vote modules installed and activated.
I want users, including anonymous guests, to be able to promote content to the front page after it has been published, and also to demote it. These actions I have created in voting actions.
I remember there being, somewhere, a page where I could specify who could vote, and also whether they could vote on their own work or more than once. I can't remember where this page lives! However, I did set it to being that anonymous people could vote, and that people could not vote on their own work or more than once.
When I'm logged out, stars appear at the top of content. When I'm logged in, arrows. When I try to vote, nothing happens, and this is when I am logging in as another user to test voting.
I'm configuring voting for the first time while building my testing site at nywf.5gigs.com and so I'd love your help. If you know what I'm doing wrong, or could suggest what I could do to make voting work, please let me know!
