InterPoll is a Web-based service which allows anyone to conduct a poll on any subject. InterPoll allows for various voting mechanisms, from the simple "vote for your favorite", to ranked systems, such as "pick your top 5 in order". Voter verification can be done in a variety of ways, from "open" voting, to restricting to registered voters with valid e-mail addresses.
At this time, InterPoll is strictly non-commerical, and currently in Beta testing. If you would like to conduct a poll, ask questions, or discuss features, send e-mail to oneill AT oinc.net. Commercial use of InterPoll could happen in the future, but not yet.
