For those interested in Masonic Stamp collecting there are no associated forums but here are three (relatively) new resources which are currently being expanded:http://www.mscnewyork.net/
Although the Masonic Stamp Club of New York no longer accepts members it's entire repository of publications has been digitized and is available on line.http://www.gwmasonicstampclub.com/
The George Washington Masonic Stamp club is still active and meets yearly at the George Washington Masonic National Memorial Alexandria, VA. http://www.masonicstudyunit.com/
The Masonic Study Unit (ATA/APS) is active and has a new home on the web.
Although a bit dated there are also two ATA Publications about Masonic Philately available. There has been some discussion of updating both.
ATA Handbook 141 - Masonic Philately (USA & CANADA)
ATA Handbook 145 - Masonic Philately (Government Issue)
