It is ok and no harm done if you do not know the abbreviation of Physician Assistant. I am not getting to you on that, but reposting your question after someone else had answered it for you with links in a previous post is another thing. Even the time frame was long enough.
Thats fine and dandy that you are getting into the PT field but one thing you failed at was not checking what you last wrote and seeing if someone responded with your answer. Then, you go out and write a new thread on this issue claiming to have a difficult time finding it. There are search engines such as Yahoo, Google, Hotbot. If you would of typed "PA" "NP" then it would of found you information. There is also Search SDN Forums option right smack at the dam top
