Hindi is our national language and is spoken by majority of people. And i feel, there's nothing wrong in writing Hindi here in forums. My mother tongue isn't Hindi; but that doesn't give me the license to say derogatory remarks about the national language. If i try to communicate in my mother tongue; there are minimum chances that u people will understand. So i usually use English; and some times Hindi.
MR Ganeshan; why dont u protest before ICAI to make ur language as a medium to write CA exams?
