Looking at my Blackberry a few days ago I realized I had a text message from a local president (see pic) stranded on a flight on a runway in NYC. I responded to his text and got the immediate response: “RU new 2 this”. Apparently, it is not correct text etiquette to respond using full words, as I had done. I routinely use full words with Instant Messages too. Decided it was time to learn the new language of text messaging.
Here is a text messaging abbreviations “dictionary” I found online (although I have no way to know if these are accurate).
BTW, 4COL is text meaning “For crying out loud”.
