Jeff Sackmann question forums?

by RWO » Wed May 11, 2011 6:40 pm
Hi,
I bought Jeff Sackmann challenge set last week and while working through them I found some answers questionable. I browsed through their site but didn't find a forum to post questions.Also I am not able to find those questions over net to verify my answer. Does anybody knows if their is place where we can post his questions? I am not sure if I can post them here in BTG.
Any help would be really appreciated.
