Polls and flags

I want on the homepage you can see more polls instead of 2, is possible?. I would also like to know if some members can be reported with a Flag so as to make such verified, is possible?

If you using 6.1.x, I can refer you to

templates\base\scripts\BxBaseIndex.php

you will able to find in

function getBlockCode_ProfilePoll() {

LIMIT 2

you can change it
