I've been wondering this for a while but is there a list of how you earn points at all? I've been stuck on 43 points for God knows how long and was wondering what to do to get anymore points.
Your forum points/trophies (as well as how to earn more points/trophies) can be viewed by clicking the points value on your profile page As reference, look for the blue arrow in this image.
Basically what poke said, there is a list of trophies/challenges which you complete then get points from. Get 100 likes in total etc
