Some of the visitors have enjoyed reading the posts but faced a problem in leaving their comments here. Most of us have a google / gmail account. We need to be signed in, in order to leave a comment. If you don't have a gmail account already, you could create one now.
Sorry for not doing this earlier. Here are the step - by - steps:
-> After you've read the post, type in your comment.
-> Select Profile (e.g google Account)
-> Click on 'Preview'
-> You'll be asked to sign in to blogger using your gmail account. Do that. If you don't have an account yet, you can use the link on the same page to create a new one.
-> Once you are signed in, you'll be shown your comment in preview mode, on the post's page.
-> Now click on the 'Post Comment' button.
And that should be that :-)
