So in the beginning activity rises slowly, but with the time, even if you post rarely it will still be growing?
It rises the same, but I guess it goes up faster if you have many more posts. If seems to go up one per post when you're a newb, but if you have many more posts than you do activity your activity will go up to 14 with one post but you still only get 14 points for that period. It's confusing and ive probably not helped but you'll get the hang of it.
