Pretty much the identical situation here. I'm part of a quad that is nearing the 2.5 year mark and still strong. We too are "making it up" as we go along. It hasn't been without its challenges, but I wouldn't change a second of the journey. Feel free to PM me as well, if you ever want to talk. I agree with Squashking in that I really value the conversations I've had directly with other quads I've met on this forum as well.
