The best method to contact Andrew is to mail him a letter:
Andrew Suh B72067 2600 N. Brinton Ave. Dixon, IL 61021
You can email Andrew here if you choose. However, it will take weeks for him to respond as a close friend retrieves his emails and later relays messages to him. The most direct method to communicate with Andrew is by "snail-mail" - up above.
You are likely picking up on the fact that Andrew is referred to by his full name rather than Andy - as we all knew him in high school. Turns out, he's always preferred his full name. That may sound strange or unfamiliar to all of us, however, it would be great if you would honor his request should you correspond with him.
