Q: Signing for the STRAWMAN looks like this: MAC?

A: No, only when you initial and date any subsequent
changes

Q. Signing for the real man looks like a normal
signature (autograph)?

A: Yes - you may wish to add the '-' and the full colon
':' but that it up to you. This distinguishes it from the normal
upper and lower case spelling which by default is assumed
to be the straw man if your name is Frank Henry Jones.
Signing as Frank-Henry: Jones by your own defination as
author means Frank-Henry of the Jones human family group
or tribe.
