1. IntenseDebate appears to be fixed and the old settings seem to have been saved — except the two most recent comments were lost. Please let me know if you have a problem.
2. I’ve added a new email option, using Feedburner. If you’re having problems with your present email subscription, re-subscribe using Feedburner. That should fix the problem.
The option is in the upper left corner of the screen. You’ll be given a choice between an RSS or email subscription. Just click the email link and follow the directions.
