It shouldn't really matter though. Whatever it uses for false,
if(!some_condition) {
do stuff;
}
stuff should always be done if some_condition is false, regardless of how php
represents false.

Nope, that didn't add Re: to anything whether it had it or not. The following
also did not work.
if (strstr("Re:",$string) == "") {
$string = "Re: " . $string;
}
and
if (strstr("Re:",$string) == 0) {
$string = "Re: " . $string;
}
Both of the above stick a Re: in front of everything regardless...
