farewell emails?

spent the entire afternoon sending out farewell emails (if that's what you call them) to people that i have known over the last 4 years in NTU... err... hmmm... lets me see to whom have i sent out the emails to:

kum wai (IA company's cell leader),
johnson (IA colleague),
and also to my fyp supervisor A/P tan yong jun (not too sure whether the email address will work)

well... besides them, emails were sent out to the usual suspects...
embassy of portugal in bangkok (why are you not replying to my email!!!!) for my visa,
dear ms sonia and mr niall power of university of aveiro (thanks to the former helping me with some enquiries and the latter totally avoiding my emails i suspect....)
