Hmm I have also noticed that they have increased the helpfull and corect answer points.
Correct answer gives you 100 points and helpfull 50 points, thats pretty much.
Also the points reset time to time but making 1 post gives them back.
I was novice this morning but 1 post and i was back at 1000 something.
Well it will still take many posts to get back to the near 5000.
But points are points they really don't matter anything.
