In index.php, replace this:

// get newest member
$getnewestusers=$DB_site->query_first("SELECT userid,username FROM user WHERE userid=$numbersmembers[max]");
$newusername=$getnewestusers['username'];
$newuserid=$getnewestusers['userid'];

with this:

// get newest member
$getnewestusers=$DB_site->query_first("SELECT userid,username,field9 FROM user LEFT JOIN userfield USING (userid) WHERE user.userid=$numbersmembers[max]");
$newusername=$getnewestusers['username'];
$newuserid=$getnewestusers['userid'];
$newuserlocation=$getnewestusers[field9];

Now use $newuserlocation to show that field in the forumhome template.
