Until further notice (actually beginning last night), commenting is disabled. The spammers have been attacking the Ektopos server, and the host is trying to find a better solution. I hadn't been able to log in to make this known until now. I still can't leave comments, so that must not be resolved yet.
Update: Comments appear to be back as of 12:30 pm EST. You now need to enter a security code, and TypeKey seems to be enabled. We previously had a link to log in, but it didn't work before.
