Wikipedia is an information site where you get all your queries solution.Its a trusted website where you get all the information based on your subjects. As you posted some queries there you will definately get a good answer. I used most of the time wiki how and it gives good results everytime. sometimes users give sensable answer and sometimes not but u definately get a good idea as u once posted or comment post.This website is really fast and also you will get the fast solution too. I always prefers wikipedia once you are in confusion
