Have replaced an episode (confirmed by email to the effect that "Long Tail Publishing has been applied", but the old version of this episode still appears when I click “Link to media hosted on Blubrry.com” when I edit the post on Word Press (I can tell because of the difference in file size). I can’t see whether this is a problem on Blubrry or on Word Press, as so far as I can see I can’t check the file size of my uploaded episodes on Blubrry.
