First of all welcome to the forum.
To answer your question YES there are US based forums (see below)
http://lists.thesmokering.com/mailman/listinfo/sausageYou will find several of the same names from this site (mine included), though personally I feel that this site is laid out better. Though I visit both sites however, I spend most of my "forum time" here. It's up to you to decide which suits your needs better. Look forward to seeing you participate.
hope that this is of some use to you
kind regards
