Welcome to our forum.
It's always good to know when someone can be open-minded about polyamory, even if it's not a thing for them personally. You will find a lot of good information on this site, and be able to learn a lot about polyamory. If you have any questions, don't hesitate to ask. By the way, I think the standard derived terms from polyamory are polyamorous (adjective) and polyamorist (noun).
Good to have you aboard.
Love means never having to say, "Put down that meat cleaver!"
