There's definitely a couple of 72 builds on the forum but can't remember who.
When's the official b'day, sept? Would be nice to maybe do a commemorative badge. I quite liked stork's tribute badge but afaik noone's heard from him for ages now.
A few GTGs around the globe would be good to. No regional GTGs, one per country, eg, All aussies to meet in the middle, GTG at Ayers Rock
