So, a number of people have written to me to let me know that comments don't work on the Server WG blog. I took a look at it today and discovered the following:
1) Logging in with OpenID first seems to allow comments for me. I am unclear on whether that's limited to admin users. 2) Disabling the WP-Spamfree plugin restores functionality.
I'm inclined for the time being to just set all comments to moderated and disable the Spamfree plugin. Any opposition?
