Shoot him a PM .... he might have email enabled to receive a notify. That's how someone suckered me back from a hiatus....
Damn you Matt

....
I'm sure his email is probably available to someone with access to the database too fwiw.
Or just find him via Google

.... wouldn't be hard imo.
He is missed.... level headed and a great guy imo... hope he is just taking a break.... it's good for the soul.
