Its not the 'amount' of reps you have received. When someone reps you they give you so many 'points', the points are calculated by how many posts and other factors. The points score is then divided and you get a green spot for every so many points, hope that makes sense
Hmmm, yesterday a member gave me a pos rep, so, should that affect it?
Before that, the last pos one I got, was Dec 4th, so could you please tell me why, over the last three days, my green squares have gone from two to five?
