go to the top of the webpage an look for profile ,once you get there then you go to private groups, after that then you got the 'find existing group' and type in 'Commander Dog Army' for the groups name, then once you get to the home page go to the left hand side of the screen and click join group. If this is con fusing then go to youtube and look how to do it there. This is the easiest way i have found so go ahead and give it a try.
