I didn’t saw any user role poll restriction in your software. I wish to find anoption among others to votes only the logged users and another option to can votes everyone user. Maybe to could votes users from a specific area it would be very usefull.
Generally I find the user poll restrictions problematic. This is very important. If I am right, in this are needed changes or new options to your software.
There are and others but they are not so critical.
