Creating a "unrated by you" view

I want to create this, too.

I've managed to create one that lists any node that hasn't received a rating yet

How did you do that? Could you tell me please?

I don't know, if it works, but at Views -> Filter -> User there is the filter User: Current: "Filter the view to the currently logged in user."

so this might work, maybe?

I think I managed to only display items, where the current user did not vote yet:

• Relationships
  • Node: Votes
    • "Require this relationship": no
    • "Value type": No filtering
    • "Vote tag": Normal vote
    • "Restrict to current user": yes
• Filters
  • (Votes) Votes: Value
    • "Relationship": use the one from above
    • "Operator": "Is empty (NULL)"

Unfortunately, it doesn't work to let users vote directly at this View (they have to visit each single node), as mentioned here: http://drupal.org/node/427698#comment-2084088

Per how to create a view of nodes not yet rated, you'll need to establish a relationship "Vote Results" and then filter for nodes where "Vote Results: Value" is empty (NULL).
