To stimulate your interest I raised the size of payments to 3000k per registration (no difference if it's your your your friend that you asked to register)
so
register yourself - get 3000tc
register 1 friend - get 3000tc
register 5 friends - get 5x3000tc + 5000tc bonus = 20000tc.
That's how it will be going. Till Deadline - 24th of October
