If you’ve been expecting to receive email notification on new comments posted on entries here, you haven’t received any today. That’s because there’s a problem with the mailserver I use. I emailed tech support and hopefully they’ll get back to me soon. I have a backup that I’ll try to use for now.
I thank you for your patience.
Update: I think I’ve got this fixed. If you’re not getting notifications, i.e. you’ve posted a comment in a thread, see new comments after yours, and you didn’t get an email about it, please let me know.
