Hello, Irfanhamidk, and welcome to Wikipedia! I hope you like the place and decide to stay. Here are some pages that you might find helpful:

I hope you enjoy editing here and being a Wikipedian! Please sign your name on talk pages using four tildes (~~~~); this will automatically produce your username and the date. If you'd like any further help, contact me on my user talk page or put a {{help me}} template up on your own user talk page and someone will be along to help you. :)

Also, when writing an article, you want to look around to make certain that you are not reinventing the wheel. :) For instance, I saw that you are writing an article on coupling in your sandbox. You will likely want to look around and see what articles already exist, such as the coupling article then see how they can be improved or where your article would best fit (perhaps a focus on particular types of couplers would be better, which seems to be where your article is focusing). Again, welcome! Banaticus (talk) 13:22, 1 November 2011 (UTC)Reply
