225448 simple php

Hello! I have a script ([login to view URL]) its a community script. I have disabled the TinyMCE WYSIWYG editor in it. And now its the default input form. The problem is, in PMs if you input this: Hello, How are you. It will output as Hello, How are you. (see the user will press enter for a line break but it wont show up like its inputted) i had this work done by a different programmer once, he said it was some rule in the php on how its stored, but im sure its a very simple fix.
