He'll turn up. His last post by my time was on 30/4 at 2:22pm, and it's now 2/5 at 10am or so here (my timezones not quite right on TechIMO, though). So that means he's posted since Sunday.
Doesn't mean he's back in the States yet - maybe he stayed longer with his wife. Last post was about a new drive he installed for her, so maybe he was still there then and is on his back / sleeping now.
If we don't hear from him in another couple of days he is either real busy (Vass???

) or still up there.
Nice of you to worry about him though, Neostar. I'm sure he'll be touched.
Cheers
Mick
