Please add this list to the OP. Had a hard time wading through the forum pages to find this. It doesnt work with just the three nodes mentioned in the current OP. Also, is there a slack channel for GUN? Or is bitcointalk the preferred medium for communication and discussions?
We have several updates under consideration right now and some in work that will incorporate a few seed nodes in to the code - so all of those will no longer matter. We hope to have it ready in a few weeks. Thanks for the feedback. Yes, it probably would have been a good idea to include this a while back. All documentation will be updated after the fork as well.
