Long ago in a world far far away....
I did a DIY SWMline (and soon DIY SWM16) What does it get me if they recognize it?
I had a SWMLNB through the test group and had a tech out who didn't know/bring the needed hardware.
Later I had some engineers out and they told me I'd just upgraded to SWM. I explained I hadn't, but it seemed my account had recently been changed to reflect it.
It's always better to have your account show your system type/features.
