Welcome to our forum.
"Living in Madison, the pickings are slim, so far, and we don't truly know how to go about starting to find people who are poly so any help would be great ..."
Some links you could try are:
The first three of those links go to yahoo poly groups in Wisconsin, the first two links to groups in Madison. The fourth link goes to Polyamory.com's "Dating & Friendships" subforum. The last four links go to some promising dating sites.
Hopefully some of that helps.
