LI Weddings...Question regarding Polls

I was just wondering if you were planning on altering the way the polls are taken on the home page. Every time I call up the site, I am given a fresh ballot to cast a new vote. Do you have the capability of locking out the poll once you`ve voted from a given computer? Many other sites only allow for one vote to be placed from a computer, then you are always shown the results instead of a fresh ballot. It`s not a big deal ... I know I can find the results in the archives ... I was just curious.
