I was not sure how to submit my entries in the google form. I could not find any space there where I could have posted my comment. As you wrote-

We like to see some commentary with the links to the articles. I would recommend using the long form instead, until you've had a couple of submissions accepted, so that you can see how your submissions transform at publication.

Now, I have some understanding of how to do it. I think it would be better if you provide tutorial for the same. Thank you.
