poor people must die!!! so i thought the only place that there's no difference between poor and rich is internet. but now i noticed that only people who pay some money can have avatar and signature! i'd pay if i could, but i couldn't pay any money for online shoppings. i know you even don't bother to reply to me,since i'm not so rich. this website is for scientists and students, how come do you expect a poor student to pay money?
