This thread is only for asking doubts.....the answers to these doubts MUST be given in the separate answers thread which i have created....

i will be constantly updating this list with more and more doubts.. while replying to a particular doubt...please mention the doubt number and give ur answer...
scheme for awarding points...

....if any one else also has some of these doubts that are in this post...then i advise u to also rate those ppl who have answered following the scheme given above... now u guys can also post ur own doubts....but follow very strict rules...if u are having a doubt give the doubt numbers sequentially...following those who have posted before u...also if u have any new doubts to add DO NOT edit ur previous posts...but give a fresh post... in the answers thread while answering doubts plz refer to the doubt number while answering... and if u have answered a doubt it would be advisable to nudge the person who has asked the doubt...so that he/she will get to know...
