Let me tell you a story mate- Some years ago I began posting CM tactical hints and advice in a forum, but kept getting kneejerk criticism from a minority of whingers, and when one of them posted saying "What right do you have to try to tell people how to play CM, who do you think you are?", I replied- "I'm the Rugged Defense CM ladder leader, who are you?" which silenced them at a stroke..
So ever since, I've occasionally had to mention my credentials to let people know that not only can I talk the talk, but I can also walk the walk, and that the newcomers who I train up can be fully assured they're in good hands..:)
"..Neither do people light a lamp and put it under a bowl. Instead they put it on its stand, and it gives light to everyone in the house. In the same way, let your light shine before men, that they may see your good deeds.." (Matt 5:15/16)
Personally I wish
