Due to Earthlink's spam blocker not functioning properly, if you use an Earthlink email address you will need to configure the Earthlink spam blocker to allow email from hawkdawg.com.
As you can see from the screen-shot below, when sending email to an Earthlink user it is required to fill in the form to ask for permission to send email to that user.
In order to complete the form one must enter the letters shown in the CAPTCHA, but as you can see the CAPTCHA doesn't show so the form can not be completed.
I have tried this in four different browsers; Firefox, Internet Explorer, Opera, and Netscape - all with the same results. The audio request does not work either.
