It is the largest collaborative effort I've ever been involved with...and oh, such a worthy endeavour! I've loved some aspects, though I have a page of notes of things to remember for next time. Mostly I'm amazed that a group of regular people, with a vision, can bring a project this large to fruition.
I just played a small role, mostly focusing on a couple of smaller bits, but am getting excited to see what has only been hashed over by voice, and poured out in ink on paper, come to life.
I hope to see you there!
