Let me know if you are still having problems.
UPDATE: OK, not yet. But we’re working on it.
UPDATE 2: Admin Guy says “getting closer.”
UPDATE 3: Admin Guy says “Fixed one issue. Now for the next one!”
UPDATE 5 BY PATTERICO: OK. First let me apologize for this. In dealing with a spam problem I took actions that broke the blog. Admin Guy has been working hard to fix my mistakes. We are aware of the problems with comments identified by nk: specifically, that recent comments are not working, that people keep having to sign in anew to comment, and that the layout is screwed up. These are only some of the remaining problems but I have asked the Admin Guy to focus on them in that order. We (meaning he) will keep working on it. In the meantime I appreciate your patience.
