Following the question raised in post 73 of "Do Our First Names Have Significance?," I thought it would be helpful to start a thread where emotes and shorthand expressions could be found in one place. While many or most of these might seem common knowledge, we do have a very wide age range of residents so there might be people too embarrassed to ask. Hope you find this helpful.
Please add to the list if you know more that are commonly used.
