this place is ok, but there are quite a few that are a lot better. CSP forums, for instance, TheHighRoad.org used to be superb, but has fallen off a bit. Glocktalk is good, so is TheFiringLine. ARChatterbox is pretty good. Depends on what you want to focus on, I can name many others.Let me know? Or you could just ask ME what you want to know! Only half kidding, I've been doing this for over 40 years now, there is not much that means anything practical that I don't know or can't find out real quick.
