1. First year you get 1 power, then every year
+1 power

2. 2013 - 2005 = 8 (If the join month is before
the present month then +1 power)

3. Bonus: When you earn 3000 points, +1
power

To be more precise,

1. Every anniversary date +1 power

2. Is not the join month, its the join date.
Eg now is October. if u join 28 Oct, your power will not increase before 28 Oct but will increase +1 when date is 28 Oct

3. Power increases by 1 for EVERY 3000 points. ie if u reach 3000 points, power +1.
Reach 6000 point, power +1 to your existing power, etc...
