This was educational, especially all the abbreviations and acronyms that exist in "IM shorthand". It's amazing how new languages pop up and I dare say that "l33t Speak" fits the criteria for at least a sub-dialect.
The IM service that I chose was Yahoo, under the name "Kelley_M_Anderson". This was mostly out of convenience's sake since I already use Yahoo for email. Once I logged in, the 1st person that I could think of to IM was my Nephew, Graham, since he's always texting messages. However, he's offline at the moment. And, it occurs to me that he may have already gone through his minutes for the month, since he's always texting messages.
