Is it possible for you to give us more information on the kind of feedback you would provide?? For Indians, the $100 donation would still be rather steep, even if its for a good cause.
Advertising not allowed. You have been noticed advertising a for-profit site earlier that tanks your credibility by a huge extent. You may put this site in your signature and help out people here through your posts if you're genuinely interested in helping. But one more instance of advertising and we'll put your websites on permanent doubt.
