Thanks bạn. giá mà có nút thanks nhỉ

[linhdic]

Thanks Bạn,nhưng mấy cái summary lý thuyết về chapter I,I,III.... Admin lại delete thread. mình nghĩ đọc cái đó rất có ích mà ta.
Admin re-open thread viewtopic.php?f=21&t=568 lai dc ko vậy ?

[tvn]

Chào mọi người,

Không phải là do admin xóa đâu, mà do forum của mình bị hacked nên restore lại DB tháng 6 nên mất khá nhiều bài.
Admin đang nỗ lực up lên lại đây hix

Mời các bạn xem thông báo Thông báo về việc mất môt số thông tin thành viên và bài viết

Mọi người thông cảm chờ nhé.
thanks

[linhdic]

Trời.Page hay vậy mà ai hack chi ta.
Admin cố gắng làm lại nhé. Với lai mình nghĩ có ai đã thi và chuẩn bị thi thì cũng nên vào đây chia sẽ kinh nghiệm làm bài trong năm 2011 này dc ko.
Nice days.
