Jomsocial users and community polls

I'm currently using community polls v2.0.0 and i added the polls from the back end. Now i'm trying to vote on a user using the polls but i can't find how to select an user and then vote on the polls. So i need the users in the site that can have the option of selecting users and vote on any poll published. For example if i have an student and i want to vote on the student by using the polls and the other users in this case the teachers will be voting on the polls. The teachers will need the option of selecting the student and be able to vote on the polls that have been already published. Let me know if this is possible.
