Hey what does the star above ur profile name indicates??

I think the star indicates our rating. But i m not sure, confirm it before believing me. and if i m wrong please correct me and also tell me where could we see our rating. I want my rating to be 500 as soon as possible because after that i can post a picture with every response which makes response interesting and also makes more money.

I think it show how much we are active in this community.
