Abbreviations...that's what now a days most youngsters use. Not only in forums but in Text messages and even now a days during their school exams. I have seen example papers where kids wrote, you as in "u", and some other words which they cut down.
It has gone so advance that if you are not aware of them, you cannot make any sense out of it. It's almost like a new language to me.
Anyhow, not going into too much detail, the question for this thread is
What abbreviations you use and what is the meaning of it?
TNP - The next person (recently found out to be honest )
You - You
