I want to purchase this community poll but i have some questions:

1) is there with the component a module where you can put most popular or most voted polls ?

2) what do you mean with private poll ? user should register before voting ? because in the demo i did not register but i can vote and how the system can recognise that i have already voted if i am not registred ?

3) How can we vote only if we are registred ?

3) why all ip adresses are 0.0.0.0 ? because of anonymous ?

4) also and more important i want to make a poll where for any user his vote will be taken into account for only 1 month, after 1 month the vote of this user will be not taken into account. is it easy to make this ?
a vote of user taken into account for only a period of time ?

Thanks a lot
