I don't know what happened. I had 17 email readers and now the counter says 0...I had signed my own email address to be able to see if my post went through and I haven't received one since I posted my owl card.
So if you had signed up for the emails please try again.
ETA: I just signed in on Feedblitz and their counter says 0 too, and they used to have thousands of subscribers. Seems like it has something to do with them upgrading their stuff.
I'm not going to worry about this ;) better use the time to make cards instead of worrying!!!
