Discuss: MHS members ranking is done on what basis?

This thread is to discuss the opinion poll topic 'MHS members ranking is done on what basis?'.

Hello friends,

I have joined MHS recently and have got my member ranking too. But I am not able to understand that these ranks are alloted on what criteria, because I have seen
many members with zero points (bronze level) but still their rankings are very good and many members who are in Gold level are way behind in ranks.

Can anyone please explain me the reason for it?

Regards,
Tasneem
