# Commenting

I love comments and feedback. I always wait for a comment to appear on my dashboard and the things to pop in my mailbox. Below are some easy guidelines to comment better:

- Be polite. Write to the topic. You may not use objectionable words, however critics and spicy comments are always welcomed.
- If you didn’t understand any facts in an article, you may ask me to elaborate by mentioning the paragraph.
- If you don’t own a gravatar, an image which is shown with your name, then you may visit gravatar.com and sign-up for a Gravatar account. Well, it’s not compulsory — it’s just for fun.
- You can add an image to your comment by typing the image url. When moderating the comment, I’ll contest that url into an image.
- To insert a YouTube / Vimeo / TED / VodPod video, just enter
`[servicename=http://videourl]`

For example to insert a video of YouTube, type [**youtube**=**https://www.youtube.com/watch?v=kYqHcNDY9kg**] Above will render this:

You may use LaTeX codes to write mathematical formulas into comments. Use following pattern to write a LaTeX code:**$** [Your LaTeX code without bracket] **$ **.

For example, to write

just type

$\dfrac{1}{\pi} = \dfrac{\sqrt{8}}{9801} \displaystyle{\sum_{n=0}^{\infty}} \dfrac{(4n)!}{{(n!)}^4} \cdot \dfrac{[1103+26390n]}{396^{4n}}$

- If you wrote something wrong/inappropriate, then remember that you can neither edit or delete your posted comment. So, if you need to improve it — just write another comment or tweet me a mention @wpgaurav or mail me at gaurav@gauravtiwari.org
- You own your comment’s copyright. You may ask me to delete your comment anytime using the same email you used in your comment.
- I respect your privacy. Your email will neither be published nor distributed. Your email can however be used for two reasons:
- To show your gravatar.
- To contact you for further feedback.
