Hi,
This is more of a heads up than anything else, but it appears Comcast Cable is denying access to hthstudios.com though the forum side seems to be unaffected. I have confirmed it is an ISP block as I was able to access the site from a proxy and went through the steps to verify. I'm in the bay area of California if it helps for contacting Comcast to remove the block to your site on your end.
