AJ, The story of the Brotherhood is a sad one. The original Brotherhood of the Ring was a group of Texas fliers that liked Ringmasters. An Internet Forum was set up using, I believe, free software. You became a member of the Brotherhood of the Ring when you registered on the Forum Site and could then participate in the Forum discussions just like the RC Forum we are posting on right now. That original Brotherhood of the Ring Forum was lost when the host system experienced a crash and the Forum was not backed up! After restarting from scratch the Forum thrived for a number of years but a few years ago they started having problems again and since the software was buggy and not being updated it was decided to abandon it and thus ended the Brotherhood of the Ring Forum.
Meanwhile all of this time the Annual Worldwide Ringmaster Fly-A-Thon has been continuing using email contacts and then the Internet Website and Facebook Group as contacts for coordinating the annual Fly-A-Thon. I have been coordinating the activity for the last dozen or so years along with running the website and administrating the Facebook Group.
As far a belonging to the Brotherhood of the Ring all you have to do is participate in the Annual Worldwide Ringmaster Fly-A-Thon and you can claim membership!!
Tight lines and soft landings,

John Cralley, For the Brotherhood of the Ring
