I don't know (yet) what happened, but something broke in the last couple of days and all the web interfaces (e.g., for subscribing, or reading the archives) to the mailman mailing list system at febo.com are currently broken. The good news is that the problem is so pervasive, it must have a simple cause :-). I hope to get it fixed Real Soon Now, and will post a note here when that happens. Sorry for any inconvenience. John
