I recently moved my blog from blogspot to self-hosted wordpress and just noticed that all of my old posts came over with the text that used to be only at the bottom of posts in my RSS feed. This text is only relevant to feed subscribers and I don't like having it on every post. I can go through and delete it from each post one at a time, but with nearly 400 that would be painstaking. Any ideas on how to get rid of the text without editing each post individually?
