Crickets? Did you mean armadillos? I don't pretend to understand the zoological aspect of Pen Posse communication.
On the other hand, I think that to support the anyone-can-call-a-Pen-Posse principle I'll plan to show up. Whether some public-spirited Facebook user will repost this to FB remains to be seen. One of the ideas Ethernautrix put forward is that you have to be prepared for the possibility that nobody else will show up.
If the word spreads, let me add as a request that I'd like to try the relatively new Moonman #6 fine nib, used in the M600S and in several earlier Moonman pens, IIRC. I hope something magical happens, we have a full house, and someone offers me a Moonman to try. I am too old not to believe in magic, disenchanted as I was at the age of twelve.
