Hello Mr Debashish Bhattcharya,
You are not supposed to post the same material in two different places of this website or two the sister websites of Bengal Spider. Whenever you are posting some resource to a particular website, after approval that resource belongs to that website only and according to the copy rights and guide lines you are not supposed to post it any where else. But you can edit the sentences and change the topic and summary of your resource and post it to some other website. Thats possible but again you need to re type the whole thing.
Thanks a lot,
