Sir,
such clarificatory explanations are encouraging all to write their views without inhibition.
Here one confusion I see may be considered in view of the following situation :
a member has posted about certain train: Food quality is bad.
Now...
more... here red or green will flow but what red or green is indicating.
1-If I appreciate food, but dislike cricism
2-If I dislike food, I will lke cricism.
Does the overall Green or Red guide the 'users' rightly ?
