As far I've explored, I can't find a mechanism to filter your responses by Points.
Coming to 0 (zero) points responses, there might be links only or some technical mistake. If you have posted Links only in a response, we might even assign negative points or delete response. If you have responses that you assume, we've done mistakes while assigning points, please message me or any other forum editor via their profile.
However, you can check your responses via Contribution tab in your profile or by following below link.
Replace USERID with your Login name.
@Arun: Member ranking system is done by CMS itself based on the contribution during the week on Sunday Midnight (expecting lowest traffic). So member level is not factor for defining Rank.
All the Best.
Glad to be,
