Best I recall from years in business, if she initialled it over her name and title, it's as good as a signature in court.
I don't think you have any idea of how right on target you are with that comment.
As an un-educated outsider, I once needed a large federal agency to adopt a policy required by my then employer. I and an attorney for the organizaton I worked for drafted up a policy and paterned it after one within the federal agency. We then sent it in for circulation and approval within the agency. The process within the federal agency was to use a routing slip to all the major department heads. If approved, they were to signify their approval by initialling within the routing slip box.
Well over the years, certain "codes" became accepted such as if a Dept. head didn't like a policy, but wouldn't fight anyone trying to get it passed, they would initial "outside the box." There were other codes to indicate various forms of acceptance, support, ambivalence, or outright opposition.
To a rational human being initialing would be the same thing as signing. To a federal bureaucrat, initialing and where one initials could make a world of difference as to what was meant.
My thoughts, too. Clinton has taught us a lot.
