Michigan State University 申請疑問 - 留學

剛剛送出MSU的申請(ECE)之後
進入status check的系統
發現推薦信似乎可以以線上的形式傳送
再看了一次系所網頁:
The graduate student portal allows you to check the status of your
application, send e-messages to the department, upload various required
documents, and request letters of recommendations.
這是代表用線上形式的推薦信嗎?

因為網頁下面又有:
Three Recommendation Forms must be completed for domestic applicants by
instructors or supervisors familiar with the applicants work. The e-mail
address of the recommender must be provided on the form. Please provide a
copy of the recommendation form to the recommender. For applicants from
international schools, a signed letter of recommendation on official
stationery from the recommender's institution is required. For both domestic
and international applications, the reference material may be submitted
on-line.

這樣是代表紙本還是線上形式?

不知道有沒有人已經問過相關問題

先謝謝大家
