The Write wizard is not part of the Newfangled set. It was written and submitted by a mach user.
If you look in some of the general topics you will see lots of discussion about Write. I believe there are two true statements. 1) write does really work, 2) Everyone has a big problem using it.
The good news is that the new version of the newfangled wizards, which is now about done and ready to ship, does have a write function that is easy to use and works well. I have posted a couple youtube videos showing how the new wizards work, but I have not detailed the engrave function yet. It will probably be in the next video, maybe in a day or two. See the topic inthis section for discussion of the V4 wizards.
