Welcome to our forum.
Another book I've heard *very highly* recommended (I haven't read it yet, but probably will soon) is "Opening Up: creating and sustaining open relationships," by Tristan Taormino. Something to look into perhaps.
We're all newbies at poly when it comes right down to it; it's such a "new" lifestyle and one has to dig to find the support for it (let alone the research on it).
But you should be able to find some good friends and good company here.
Welcome aboard ...
