The more I've messaged on MySpace or Facebook, the more technologically illiterate it seems I've become. For the past few weeks, I've tried to decipher what people mean when they write :D or :P at the end of their sentences. I only know :)  means smile and :(  means frown.

The other day, my 16-year-old brother instructed me to use ;)  for a wink. I always thought ;) was just a typo as someone attempted to :)  My brother also told me LOL means "laugh out loud." I had always used it as "lots of love." Which definition do others think is correct?

What are some of the other common IM or text message symbols that you use? And what do they mean?
