So, people can sign up under others, and have 5 different levels in that, eg:
I sign up
user 2 signs up under me
user 3 signs up under user 2
user 4 signs up under user 3
user 5 signs up under user 4
Now, i have to store this, because when user 5 takes an action, user 4,3,2 and 1 should be credited.
I can code it, but i, a bit lost what kind of structure i would use for this....
Could anyone give me a hand?
