Definitely agree with BoringGuy - spend the time to read the "Life Stories and Blogs" section and you will get a great cross-section of the different types of poly relationships that are out there, and some of the typical issues that can come up. Bear in mind, however, that this is a skewed sampled - there are a large number of poly folks who are quietly "getting on with it" who never ever post to an online forum. most folks come online to post when they have a problem, so I think that you will see a disproportionate number of posters writing here who have issues.
You will get lots of impressions of personal views and values from reading there..
