Comments Update
I have contacted Hosting Matters Technical Support to see if they will re-enable commenting on the blog(s). In order to get this done, I have enabled Typekey authentication. This means, anyone wanting to comment will have to register for a Typekey account. I apologize for any inconvenience, but I'm not sure how else to stop the comment spam flooding that led to comments being disabled in the first place.
UPDATE: Comments are back up, but with the aforementioned registration requirement.
