The bulk update request #5410 is pending approval.
create implication autograph (176) -> signed (0)
create implication signed_photo (18) -> autograph (176)
create implication signed_document (7) -> signed (0)
Reason: This is to use the signed tag as the overall tag for anything that has a in universe signature in it. reason I didn't suggest signed to be aliased to autograph since it is situation specific.
