well i'm only speaking from my own experience. i have sent thousands of resume's by email in my time and the best responses i get are when i've sent tangible resume's. and tbo i don't care about the evironment until i have a job that can sustain me. it's hypocritical but until i have life sorted it's not important....and after i have a sustaining situation then i can be eco friendly.
EDIT: of course indi you WOULD be the exception to the rule hahahahahaha.... ye right....like i believe anything you say hehehe....director hahahaha
