I was looking for a rating plugin for a competition. It was important for us that we have a good backend/statistics of the voting/rating, but the online audience should not see neither the results, nor the number of votes, as this should be the surprise until the end.
Vova helped me through several steps of customization with immediate repsonses via email. great support!
And even when paypal did not work he upgraded me directly.
Thanks for that!
