I’m checking to make sure petronski has not visited this thread!
Well, as of this moment there have been 3,372 unique views to this thread but only 66 posts (67 with this stoatpost) so unfortunately there are at least "a few" folks who dropped by but did not 'mark their territory' with a post, as it were :-)
I suppose that a list of IP addresses could be had from JimRob with a court order, and various forms of forensic analysis could be employed to pin Dr. Petronski to this thread at a particular time and place but all of this is beyond the purview of someone like myself.
I'm guessing that Geraldo Rivera would be the perfect person to contact who could provide you with an rock-solid answer, providing he's given an exclusive on any other dirt he uncovers, of course........
