Ethical Issues

The plugin works great, but a couple of ethical issues I wanted to raise:

When activated, it seems the plugin mails the developer to track what sites it’s installed on.
(mail($authEmail, $subj, $msg, $headers);)

More concerning though, it seems that it’s adding some links to fastemailsender.com.
($authSite = ‘http://www.fastemailsender.com’;)
Just wanted to find out why this is necessary.

Thanks!
