I used the following code in functions.php instead of the code you provided.

PHP Code:

        if (THIS_SCRIPT != editpost) {
            global $bbuserinfo;
            $replacementvars['/\[you\]/i'] = $bbuserinfo['username'];

        }
            $replacementvars['/\[test\]/i'] = "This is just a test."; 


Reason I did this is so that its not parsed on editpost so that when you edit a post that contains it you dont have that nice problem of it locking in on your name. Also so you can tell when other users are using it faster and easier. The reason for the [test] code is since that it will allways be looking for something to parse out so on edit post you would get an error becuase there would be nothing to parse out since the error checking code was removed when this hack was installed.
