leaving that last user added to the file not to match since it will not have a
\n at the end of it...
adding one to the user as it is added into the array results in yet another
array element after the file() since it reads the additional line as another
array element.

thats the crux...
fwrite ($fd, join('', $users));
results in a long string of usernames in the, which can't be grabbed back into
the array with the file... in short, there is no way to trim as you file() to
eliinate this (from what i can see) other than running it through each() or
something and rebuilding the array after trimming. Was hoping for something a
little more eloquent.
