Change Date

While editing the post check the “Edit timestamp” box AND modify the date. Save it. Don’t forget to check the box – otherwise it doesn’t work!

Thanks. Sounds like it will work but, where is the Edit timestamp box? I am in edit mode from the manage page, but I don’t see it there or when you are editing from the write page.
