If you want a reference letter from me then you must satisfy any one or more of the following criteria
If I have agreed to give you a recommendation letter, send me an email with your recent resume in plain text, the list of places where you are applying, university stationery if any, and stamped, addressed outer envelopes. I will mail the letters directly. It is your responsibility to send me a reminder on time such that if I ship out the letter from NTU the day you remind me, you can still make the deadline.
