What type of homepage is it?

Assuming it's a non-vB one:

PHP Code:

$conn = mysql_connect("localhost", "username", "password") or die(mysql_error());
$query = "SELECT pagetext FROM post ORDER BY dateline DESC LIMIT 1";
$result = mysql_query($query) or die(mysql_error());

while (list($pagetext = mysql_fetch_array($result)))
{
    echo $pagetext;
} 


Please note that this is the simplest possible way and will only output the latest post text and nothing else. You might have to add a table prefix also if you use any.
