"Chat" has a language all its own...
There are words that have been newly developed for this unique environment, abbreviations and acronyms to save time
typing, and emoticons to clarify the tone of the text.
Once you start chatting regularly, all of the terms, etc. that are included in this
section will come naturally, especially if YOU start using them (and watch out, some of them will sneak into non-chat correspondence <s>).
If somebody uses a term or symbol you don't know... just ask them what it means. We were all "newbies" once.
