You must understand that XI lives in fear of losing to their guests and hides all secret information so as to give themselves an advantage.
However I will divulge the activate stuff.
Be sure Console is allowed in your game settings.
Bring down Console by hitting your Tilde Key ( ~ )
Type in /+activate
Hit Enter
Hit Tilde key again to close Console.
You are good to go.
Remember, the activate messes with your use key. You may accidentally pick up weapons you do not want and won't open doors like you did.
However the key you use to bring down your map, X key I think, will function like a Use key to open doors and change weapons. It's a little inconvenient but well worth the benefits of the activate command.
I also have a small, removable dot on the exact center of my monitor, with that dot I never have to aim at someone to thaw them. If my dot is on them I am aiming at them. Also helps me in firing from the hip. I use a small spot of Whiteout for the dot. I have been using this dot since back in MoH days to get around the loss of cross hairs in Hardcore mods. I dare say a few XI have even begun using it.
It is flattering to know that XI is so scared of their guests skill levels that they had to move the secret stuff to the member area to protect their advantage. I shall take that action as a compliment to the play of their guests!
