Woot! FJC FTW!
I'm 46 years old and never paid much atention to computer/text acronyms untill I started playing MMORPGs lol. If you don't know what THAT is, you might as well toss your computer in the trash and just hit the trails.... I mean, wouldn't you rather be off-roadin' than readin' the forums? lol j/k. It is indeed good to know and understand acronyms, since there will be a time in the future where everyone will be expected to know most or all of them, and they're more made every day.So put on your jogging shoes and try to keep up.
