This is a very nice and professional made plugin. Works just fine.
But this is a free basic version without these options:
To get rid of the (i) report button
To get secure connection layer to prevent impersonated fake voting
To upgrade to standard it cost 3 $subdomain/month
To upgrade to Premium it cost 8 $domain/month
I would wish it was like many other plugins, and asked for you to donate, or at least a "one time" payment, instead of every month.
