contact

The people that maintain the Hardwall Firewall are contactable via many different means as you can image. If it isn't urgent, you might like to fire them an email. If you would rather discuss the matter in a more fluid environment, most of them also use an instant messaging program of some sort. Of course, they are always idling in IRC on FreeNode in various channels.
