I've been suspicious of that widget for a long time. Got about 20 subscribers within a month or so of beginning my blog in February, then none. At all. Since. I tried subscribing with different email address and got no confirmation mail. Contacted support and danced around with them for a while, and they managed to subscribe, and then I was able to subscribe. But still no new subscribers. I let it go. Figured my blog just was not attracting any new subscribers (though you'd think I'd get one or two)
Now, when I just put up a post couple days ago, I did not get a notification sent to any of the three email addresses I have subscribed to my blog with. I used to get the emails right away, so this is a new wrinkle. Contacted support. They asked for details. Sent details couple days ago. Nothing. Sent them again. Nothing. Any help out there? Thanks in advance.
