If it's the same as fNWA, the vru didn't rotate. I don't understand the PBS thing as that was the same as the others too.
Technique only. I had a non-dictionary 5 letter string of letters and tacked on 001. 90 days later it was the same letters 002 etc. Never had to write it down and if I forgot where I was, I was never off more than one number for the retry.
Anyway, I hope they open up some other areas of they system with this supposedly more secure system. We'll see.
