as student of electrical engineering you should be a bit more careful about editing wiki documentation. Your last changes to Help:Concept demolished page and are rejected. --Rajko m 10:29, 19 May 2013 (MDT)
Dear Mr. Rajko,
I am sincerely thankful for correcting the mess done by me. But I can assure you that was done because I am unfamiliar with wiki editing and I was a little bit in hurry. But, I can assure you that it will not happen again.
Thank you for your time and consideration.
