I’m switching to a new system for comments, which will require everyone to register once. After that, you’ll be able to post on any blog using TypeKey for comments. But I’m not sure it’s working yet. It doesn’t ask me to register. But maybe that’s because I already am registered. At any rate, let me know how it’s working for you. If you’re able to leave a comment, of course.
I’m hoping this will defeat the evil robots that have been posting dozens — sometimes hundreds — of spam messages on my old posts.
