Welcome to our forum.
I am in an MFM V, so that part kind of rang a bell for me. Have you been able to find any poly organizations in your area? Sometimes it's fun and helpful to meet up with people live and in person.
We have a lot of good information on this site, so have a look around at our various threads, and see if you have any questions. Your input will always be welcome.
Hope you find all the things you are seeking,
