Couple of options:
1) Send the guy an IM. In Jeff's case, he's a very good guy and I'm sure he'd respond. He's a Club Professional, in a cold weather place, so he might have some free time now. The one time I played with him, you could tell by his setup and mechanics that he was a good player and understood the swing. You could also tell that he was a hard-working Pro because he was slightly off his game in some of the areas that require alot of practice time.
2) If you want to read other stuff they posted, click on their name and it will bring up a Profile page. At the bottom, it says "see xx post". Click on either 50 or ALL, and see what else they wrote on the board.
3) IMO, the search features on GCA.com are pretty weak. But, you could try "search" (top of page) and go to the Advanced section and put a few keywords in there. I've found this to be very hit & miss at finding stuff.
