[phonexpo]

I'm a bit lost on this one... :ermm:

My forum is at www.phonexpo.net/index.php & my main site is at www.phonexpo.net (welcome.html file name).

It says;

How To Use vBExternal:
First the webpage you use it on must be php, if it is .htm/.html just re-name the extension to .php
Next step is to call the file, in this example we assume that your site is: http://hello.com, and your
forum is located at: http://hello.com/forums, so insert this code at the very top of our php file:
<?php
chdir('./forums');
require_once('./vBExternal.php');
?>

So do I have to change the welcome.html file name to welcome.php ?
