# Commenting

I love comments and feedback. I always wait for a comment to be appeared 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
