Turns out there isn't a constant ammount per person. Instead, each person can give one point per/365 days as a DF member and per 1,000 posts. I think there are also a couple of other little twists, but that's the basics.
Wow, Im really confused. I was asking how many reputation points I get everytime someone clicks to give me rep. Like if it says I have 50 rep points, how many people contributed to it. I think you were saying I can only give you rep once a year? Or once every 1000 points?
