Stupid question - would surveymonkey mean one round of voting or would we still do pleminary voting to narrow things down, then the final vote?
We can do as many votes (aka surveys) as we need. It'll automatically count the votes. A workaround of iP address verification could be requiring a login to vote. It let's you use your fb / Google login w/o signing up and registering.
I just started using it on our site here at work and it's really easy to use and edit with.
