I am an Outbound program manager, Jeongwon Choi.

Due to the system preparation issue, 2018-1 Exchange Program Post First Round will be delayed about an hour so it will be posted at 12:00 pm.
You can sign the confirmation starting at 12:00 pm today (August 16th) and end at 12:00 pm on August 17th.
(It was written as 12:00 am so I edited to 12:00 pm on August 17th)

Thank you for your understanding.

Jeongwon Choi
