I can't be certain the feedburner gadget worked at all so I disabled it. It was the one that said "Follow by Email... I Think" and you entered your email address to follow. It says I have zero subscribers and I know that's not true, so if you tried to follow that way it's not working.
If you tried to follow via the email form, please instead JOIN via the "Followers...and Leaders" option at the bottom left. This one I know is reliable. And I'm sorry for the inconvenience!
