if you try it on the server i am running on you will get the hang of what i am trying to say, as long as the data is submitted as a single line in the textarea it prints out fine with the '_' break in between but as soon as you enter the text in 2 lines or more it adds '_' breaks in between every entry in the text area. Please feel free to try it your self on
