The ampersand does not make it optional. It passes it by reference...

<CODE>
//I simplified the code
function doEmail($username, &$link)
{
if (isset($link))
{
print "$link $username";
}
else
{
print "$username";
}
}
doEmail($arg1);
doEmail($arg1, $arg2);
</CODE>
Here is the error:
Warning: Missing argument 2 for doemail() in
/srv/www/htdocs/test-a/staff/email_scramble.php on
line 24
To make the second variable optional, give it a value in the argument
list when defining the function...
function doEmail ( $username, $link = NULL ) {
