在老外论坛的时候，刚开始会有很多他们的所写的abbreviation看不懂，看到刚才看到有人问，干脆发个帖子，把比较常用的经常见到的列出来, 大家知道什么都补充一些。以后当个reference 帖子

Here're some more that I can think of:

Ditto - meaning you agree whatever the previous comment
AKA or a.k.a. - as known as
B/C - because
BS - ..........
FYI - for your information
GR8 - great
PITA - pain in the ass
these are so far what i can think of... I personally dont recommend using abbreviations unless they are really widely used...
google "AAAAA" or "American Association Against Acronym Abuse", to find out why
