I have been lucky enough to work with other instructors in MD, VA, PA, DE and NC. We have always been supportive of each others classes. I even refer folks to other instructors when I know I do not have a class coming up or if the type of training a student wants would be better served by another instructor.
I think it is in our collective interest to have a forum, if for no other reason than to keep aware of changes in NRA and MSP training requirements.
I also find I take away something when I have discussions with other instructors or assist in a class.
Just my $0.02!
I'll add anothe $.02 for this.
