How to answer other people's questions

Hi, RagunandanM!

We have a Help Center article available that provides instructions on how to respond to questions posed by others:

• https://support.khanacademy.org/hc/en-us/articles/4411209335181-How-can-I-access-discussions-under-articles-and-videos 

If you still cannot find the comment section, please submit a support request in our Help Center: http://khan.co/KA-support.

Hope this helps!
