gempresario: I don't know how your campus delivers mails to students because different places have different systems so you would need to ask the people in charge of your mail about that.
Registered mail requires the recipient's signature to prove that delivery has been made. Although, it may not necessarily be signed by you - it could be signed by the person who receives the mail at the address.
MagnumMYVizt: Don't worry, we eventually figured out which country you're from
We'd appreciate it if you could include your full mailing address next time because we're posting your prizes from Malaysia.
Thank you all! Loves
