I've created a family in Archeage. It's like a "guild lite" We have our own /family chat channel, and land permissions allow you to share plots with family members.
You can be a member of both a family and a guild. This may just be perfect for our group in this world.
At least for now.
I'll invite you as I see you online. Nidous is in, not sure if others can invite or not. We'll see!
