jhp--LOL, I know EXACTLY what you're talking about, LOL. I haven't been in many chat rooms, but I used to belong to a stepmothers message board group and we'd have chat times, and I could never keep up, either, even though I type very fast. I could never catch up with the conversation, LOL.
Lee--Here are a few other things you might see. BTW means by the way, and IMO means in my opinion. Do you have those kinds of expressions in Australia?? It's funny about LOL---that phrase has even worked itself into conversation now. Every now and then, I hear someone say something funny followed by "LOL." Liz
