Sorry, but I am a bit naive as I am new to INGO. What is the INGO salute?
I would tell you, but then it wouldn't be a secret. How's this, while driving today cut somebody off then slam on the brakes. You'll know the salute when you see it. Just give it right back with a smile & a nod, then post on here about your experience to find out which INGO member you exchanged pleasantries with.
(this would be in some shade of purple, but I'd probably get the shade wrong, g/f says I'm colorblind)
