i have been going through this thread and once was a active helper too initially, only to realise THIS GUY IS A CHRONIC SPOON FEEDER. heartbreakdoctor you need to learn that this a forum where discussion not TUTIONS takes place. WE all have learned the hard way i.e. googling and wiking around or even trial and error.. you just dont waltz in for every doubt you have. I am not trying to discourage you to raise queries, all i mean is thats learning is an exciting process and hence make the best use of it rather than relying on others to guide you all the way !
