Hey guys Im using dreamweaver mx 2004 and Im working on a site that is going to have a voting poll, which means registered members will be able to vote on thier favorite video. I need to make sure that they can only vote one time for one video and no other video, just one vote per person, how would I go about doing that? I also need the top 3 videos with the most votes to automatically be updated to a leaders page, The leaders page will always show who is in the lead with the most votes automatically. I was wondering if this could be done in dreamweaver or do I have to buy a program that works with dreamweaver? PLEASE HELP!!

I'm not sure that dreamweaver can provide to you CGI features (like store vote data on server), you can find vote script or use online vote service from some site.
In voting often used practice "One IP-address - one user", so - no cheet.

you can find such scripts already written on hotscripts.com
