      If you have come into a chat room, or sent e-mails to or received e-mails from your net friends, you

have become one of the millions who talks to others in a different and short form of English.

     All over the world, every night children and the elder are "talking" online, and many of them are talking at the same time.

     If you want to talk fast, you need to use the language which is easy to understand. There is neither time nor space for you to tell others why. Why not just use I3RB (=be right back) to tell your friends you have

to leave for a moment?

      If you are interested in somebody,  A/S/I.is OK. It means you want to know your friend's age,  sex,

and location ( = place). You may get 18/F/ BJ as an answer. If something makes you laugh, say you are

OTF, or LOL (=laughing out loud).

     People want to write as fast as possible.and they want to get their ideas across as quickly as they can. Big letters are not often used, except when telling feelings, as it takes more time to hold down the "shift"
