Just wanted to welcome you to our forum.
Polyamory isn't what I'd call a widely-accepted ideal yet, so it's not uncommon for someone to discover the word after they've already identified with the lovestyle. The internet has surely helped poly people get together, but I suppose it will be awhile before it becomes a commonly-known community.
You're doing well to put communication high on your "list of relationship priorities." It's important in all relationships, but poly in particular.
Glad you could find us and join us, hope you enjoy your time on our site.
Love means never having to say, "Put down that meat cleaver!"
