I am very grateful to all your replies so far.

I guess some Lengendaries here misunderstood my question, I only asked this question because I was totally confused and bit lost. I See people with different tags and badges and all that, I just wanted to know what they did to earn all that....no ulterior motives whatsoever. 

Thanks to those that referred me to beginners forum and help, I have spent quite enough time there now learning a lot.

Please, you guys should be nice to beginners and at least help them find their feet....most of you were really harsh and that's not nice at all. In all, I appreciate you all.
