neways i can still help you
in college,
you need to make at least 3 friends in black suits (males) or black suit jacket w/ dark red pants (females) all have a llama emblem on one side of the jacket.
thats it
don't ask for names b/c they always change.
they sometimes change looks too from neighborhood to neighborhood
also using the BoolProp testingcheatsenable true cheat can add, substact, or just check who is in the society.

good luck

enter [ctrl+shift+c] to open the cheat box.
enter "boolprop testingcheatsenabled true" [just like this].
now point your mouse on your character[don't press yet].while holding shift press on the character,lots off options will appear.
[note:this will not work if you don't hold shift]
there will be an "enter secret society" option,simply prees that option and you will enter the secret society.

YOUR WELCOME
