It happens to the best of us. Today it was me.
I have somehow managed to lose control of my feedburner account. No matter what I try I can't seem to get in.
So, I have to change my RSS address. If you've subscribed to the old one, it'll probably keep updating until Google get around to deleting it. It'd probably be best though if you re-point your feed reader at http://feeds.feedburner.com/vspecialist-co-uk
