Greetings,
The script is currently hard-coded to read this setting from the List Settings for the list(s) being subscribed to.
In signup.php, you could change this:
if($cnfact=='1' || ($cnfact<>'1' && $welcact == '1')){
sendwelcome($userid);
}
to this:
if(($cnfact=='1' || ($cnfact<>'1' && $welcact == '1')) && !$nowelcome){
sendwelcome($userid);
}
Then, add the additional parameter "&nowelcome=1" to your query.
Regards
