My personal opinion is that may be forgery in in the sense that it meets the dictionary definition of forgery, but it is not forgery in a criminal sense.   If I were on a jury, I would not convict someone of criminal forgery for merely signing someone else's signature with their knowledge/approval, as the Georgia DocX employees did, for instance.  I'm guessing that's why none of the "Linda Greens" on 60 Minutes have been indicted.

When notarizations are involved, I think it's a different matter.  The LPS Nevada employees have been indicted on charges related to the notarizations, not forgery.  I'd be reluctant to put someone in prison for what they did there, though.  What they did was wrong and agaisnt the law, but a minor offense in my opinion.  Few cared about this kind of stuff until the whole system blew up, so I understand why none of these folks objected strongly or spoke up at the time.  Our culture has been a go-along-to-get-along culture where this kind of corner-cutting has been widely tolerated.  I'm probably not going to put someone in prison for doing something if I think that half of America would have done the same thing if they had been in the same spot,
