There's this thing: "the internet" on this thing there are other things called "forums" and on these forums are "posts" where people can say things like "JCCS 2014, Who's Going?"
Failing that, the old MSA standby of sticking a sheet of paper on your dashboard "slownrusty-HybridZ/ZC.C" helps those passing by who "know" that you are the meat sac making the posts.
I was driving a kid around from work....gopher job, we were talking about stuff and he saw my FSM kicking around the floorboard of the work truck.
"Oh, Datsun 240? Do you know about ZCar.com?"
Yeah, I'm there.
"Oh, really? What's your screen name?"
"You......you....you're....you're Tony D???" :surprise
I was then regaled as a gawd after his initial shock. Initially I believed his silence was fear from being in the cab with a baby-killing pederast cannibal, but if he had not said "Z-Gawd" I would have continued thing his silence was sheepish acceptance that he was about to die a gruesome death at my hands as penalty for his spoonish questions online...:devil
