export feature

Hey,
I found this:

if (@fopen(WP_PLUGIN_URL.’/simple-newsletter-signup/snsf_export.php’, “r”)){
$snsf_allow_export = true;
include(‘snsf_export.php’);
}
else{
$snsf_allow_export = false;
}

within the simple newsletter signup file and I can’t really find the actual snsf_export or the definition of the function. Am I missing something ? I find the plugin perfect to what I need it for, but the export is kinda crucial. Gimme an update on this one.

Cheers,
K
