→ treison:學弟都不懂得低調嗎
推 WillieHuang:有情有義啊  XD        這篇好像剛好是第700篇耶
→ kwhmagic:為什麼我覺得在班版貼這個是很怪的事情，沒看人家作過...
→ kwhmagic:雖然都知道找考古題 但直接轉過來是不是太明目張膽了??
推 candy79729:好東西要跟好朋友分享 這是很明顯的一件事情 OK~?
→ kwhmagic:樓上的分不出來教找跟直接轉貼的差別嗎? 不要模糊焦點。
推 huch81:雖然土撥鼠的動機只是為了同學沒錯 但是還是要注意一下
→ huch81:這個板不是指有我們系上的人會在看 可能還會有其他系上的朋
→ huch81:友 或是助教或教授 這樣直接轉錄 人家看來 也不太好吧
→ huch81:私下PO在自己的個版裡 我覺得是還OK 還沒有必要PO在系板上
→ huch81:一點建議 大家看看
→ kwhmagic:同意。編入精華區。版上刪除。
推 michael9002:恩..建議把這三篇進精華然後砍了..這是最好的辦法吧
