As many have noticed, we had to turn off the ability to comment on posts for the past few days. This was necessary to reduce our exposure during a Denial of Service attack. We have others investigating the source of this attack but in the mean time we have migrated to servers more able to handle the situation should it happen again.
You may now comment, though we have made a couple of changes to reduce the load. The comment preview has been removed, and a security code plugin added. This should be self-explanatory but if you have any trouble posting comments, please let us know.
Thank you for your patience and understanding.
