WTF? He was one poster that I never disagreed with. I really liked his firearms knowledge. (I'm also insanely jealous of his collection, from what I can gather about it.)
Well now, I dunno if anybody's gone.
We all have real lives too, and those real lives sometimes interfere with being on the computer.
It's spring, the weather's getting better, people are outdoors more, that sort of thing.
Or it's closer and closer to April 15.
The tide ebbs and flows; I'm not aware that anybody's "quit."
