Probably one o' them there "ninja-edits".
It's like Congress. I reserve the right to extend and amend my remarks/posts:
Revising and Extending Your Remarks: Once a Member has requested to see his or her remarks before they are printed in the Congressional Record (WNFF), especially those made during debate when other Members are involved, certain rules of courtesy should be followed. As soon as the Official Reporter gives the transcript to the Member, it should be corrected for grammatical errors and immediately return it so that other Members may do the same.
Extension of Remarks: Members may insert comments in that section of the Congressional Record (WNFF) entitled “Extension of Remarks,” by simply turning in to the Cloakroom such remarks with the Member’s original signature. It is no longer necessary to obtain “permission” to include extensions in the Congressional Record. A form is provided on the Leadership tables on the Floor for Members who wish to obtain permission to extend their remarks in the section of the Congressional Record (WNFF)entitled “Extensions of Remarks.” The Member may sign up or make the request of the Cloakroom. The Member on duty at the close of each day asks permission for such extensions which can include extraneous materials.
