How does the "Ranking" system work.

You can for example upload some models. (you get 20 rank points per model)

You get ranking points for
a) posting in the forums
b) someone replying to you in the forums
c) uploading a model
d) someone downloading a free model
e) someone buying a model (more points than a free model.)

Rank is based on your reputation points. There are many ways to get reputation points and they all are described here:

Together with growing reputation you can reach next levels which will increase your royalty rate. Find your level and more information here:
