Thanks sgmpatnaik & EN. Bobhc,
We can have 3 or 4 starts (Platinum/Gold/Silver/bronze, or 1*, 2*, 3*) like http://www.bing.com/images/search?q=feedback+stars+5+stars&view=detail&id=1B40ED816D334DB81550877C8B4AD1F711C5E351
When a new post is posted, the status should be ‘bronze’ and when the question is answered, the questioner or anyone (everyone) of us can change the status to silver/gold/platinum based on the answer. Every exact answer will deserve p/gold. Partial answer will deserve silver. And when everyone is doing the rating system, then the average rating should be the status of the question.
as bob mentioned, when many posters do not reply when they receive an answer, we can change the status. Also the one who answers the question can change the rating. If he thinks, the answer is correct then he can change.
Thanks a lot! - Dham
