Is there a subscription glitch?

Hello! I was wondering if there is a glitch in the system that sends daily email updates about the blog? I’ve been subscribed for a little over a year, and through 2 birthdays. This is going to sound silly, but I noticed on [name]March[/name] 29, 2011 and 2012 I did not get an update. The 29th is my birthday, and I was kind of looking forward to seeing with whom I shared my birthday. (I told you it was silly!)

Anyway, I was wondering if this has happened to anyone else. It isn’t a major glitch, but it might be something to put on the list of things to check out during site maintenance.
