It has come to our attention that activation codes are not being received in a timely fashion by gmail users. According to our mail logs, Google is throttling us due to a potental spam. Of course we never send spam, and already do most fo their suggestions. Hopefully the matter will be resolved soon. If you do find a SD message in your gmail SPAM folder, please mark it as "NOT SPAM" so Google can get the hint. :)
