haha! i'm embarassed of graal, i wouldn't tell any of my friends play it. considering most of them aren't computer nerds and lean toward the jock side

but heres my input on the thread, maybe if you reffered 1 person (10g) and they refer another person, the money doubles;

you refer 1 friend (10g for you)
that friend refers a friend (the 10g is doubled, you get 20g this time)
the friend that your friend referred refers someone else (40g, the money doubles!)
that friend refers another person (80g for you, and so on)

it would be like a branching tree...
