    Hi Pradeep,

    First off, let me say that I enjoyed your blog here. It helped me heaps. Unfortunately I couldn’t find a contact us link so I don’t know how to get in contact with you other then through one of these comment posts.

    Anyway, the point is thank you for your writing. But I do have some suggestions, how about including the date of a blog post so that users can easily find out about the age of the post; and may be some RSS feeds so that users can again subscribe to your site for regular updates.

    Oh! and maybe a contact us link would make it easier to contact you as well.

    Once again thanks for your writing.

      Charles thanks for the comments you have raised here which iam going to clarify for you.

      First of all we were testing some new design changes because of which the date and category link were missing but are now available at the end of the page for every article. Next regarding RSS feed we already have our email subscription box but you are right we are missing one important location to add the same which is below the article which we would do it.

      Regarding contact form, we are not going to do that because we are already getting around 25-40 emails every day from users who find our contact details and contact for their phone problems, which is why our comments section is more relevant and easy for us to handle. Still if someone has a issue they are suggested to visit our website and post their questions their.

      Thanks for the comment, because of which we are going to fix few of our missing areas and make the site more complete for the readers.

      Amit Bhawani
