MyBB Community Forums

Currently my domain I'm using for my MyBB forum is like this:

http://www.domain.com/

I uploaded MyBB files to:

public_html/root/Forum/

How do I make URL go to this every time someone goes to my domain?:

http://www.domain.com/forum/

In your site root folder make an index.php file and put the following in it:

<?php
header("Location: /forum/");
?>
