HI Mike...
A net is definitely something else. In fact this was one command I was going to use for my first Ninja Cabling presentation because no one I've ever encountered seemed to know what it was. I spent quite of bit of time learning and understanding it.
For your purposes, it wouldn't help you. There is some general information on them in the help files if you're curious but normally they're not used.
I need to work on the NWF tool a bit more but I'll send it along so you can test it out. I'll be interested in your feedback. I have to respond to someone else that asked about it but I, too, have been on the hot seat lately!
Thanks!
