Top comment feature - The comment which is more relevant to question or by an expert or by an selected candidate at top. This makes it easy to find relevant answer for a problem.
Reward points feature - for authenticity of writers on quest. For genuine and honest guidance to students.
Tagging & response feature - Lets say if people want to get response from a particular person on a really important issue, number of people will tag or number of likes. This will enable to meet demand of students from mentors.
Mental or emotional support feature- For better response from all to any need of a student. We are witnessing high levels of depression in upsc circles. Forum can be a starting point for this neglected aspect.
