I tried the feature and I think somethings goes wrong or the funktion has to be expand..
"# you can choose to allow or disallow users to see the current results before voting. If set to disallow, anonymous user can never see the results. "
I can't see the result as admin/author in the node - have to use views to watch the result?
I would suggest to expand the rules to:
1. The author of the node and a special user role can view the results
2. All can see everything
The thing with anonymous user is not flexible enough.
