在邮件列表或论坛或其它地方常见一些英文缩写，比如
OT = off-topic
ANN = Announcement
tl;nr = too long; not read
AFASICS = As Far As I Can See
AFASIK = As Far As I Know
ASAP = As Soon As Possible
CMIIW = Correct Me If I'm Wrong
FWIW = For What It's Worth
HTH = Hope This(That) Helps
IIRC = If I Remember(Recall) Correctly
IMHO = In My Humble(Honest) Opinion
JFYI = Just For Your Information
对于非英文母语的人来说，会加大交流难度，不知道还有哪些常见的么？
