Shishir, welcome to ISC and as already suggested by the Lead Editor you must go through the policies and guidelines to understand the subtleties of this site. Please note that this is a big site and there are many sections and each has its own uniqueness. Once you start working you will slowly learn the things. In case you find any difficulty, please raise a specific post in forum section and the editors or members would be happy to guide you and help you. One more thing I want to tell you is that this is a site where there are many learning opportunities like taking part in contests which are frequently organised here, asking questions or answering the questions, writing articles etc. Many members have sharpened the writing skills here and I always mention this to the interested new members. Have a nice time in ISC and start your creative journey.
Knowledge is power.
