Changing the landing page for all members from index.php

How can the landing page for all members be changed from index.php to say about_us.php ???

I don't want to use index.php and nor a redirect for logged-in members.

Please help!

Anyone???

Put this in the index.php just after check_logged()

if(!isMember()) {

header(Location: about_us.php);

}

Thanks bud
