If you are good at interpreting legal language, that would be a great page to put together. You could start a thread in the Golden Nuggets forum and add to it as you find them. I started a thread there of blogs by our members here and that was fun to put together. Or you could put up a page somewhere on the web and link to it.
I nominate you to get the ball rolling on legal links!
There are also some organizations related to legal issues for poly peeps and alternative lifestyles:
Sexual Freedom Legal Defense and Education Fund
National Coalition for Sexual Freedom's Incident Reporting & Response
Polyamory Society Legal Affairs Division
