The dictionaries for this stuff is a nice idea but I really don't have that kind of time because the abbreviations are so rampant. For communication lines to work, it is necessary to try to achieve comunicating the message on the first try. Having the reader have to shoot back and forth to a dictionary makes it cumbersome and also makes the reader feel that perhaps he does not belong in the conversation. "In my humble opinion"

I don't think abbreviations are necessary on a program board such as this. For example, I had no doubt that POS really meant "positive": why would I look it up when I thought I knew that POS meant positive? The other woman's example of ED is another perfect example of using abbreviations and creating miscommunication. Another reason is that the board is filled with people, like myself, who do not use these abbreviations in our normal course of life and it would be appreciated if the abbreviations were kept down to a minimum.
