I am one of those who was unfortunate to have been stuck with nuwiki in my forums. I had been looking at this vaultwiki and converter for a few years now, really sort of afraid that it would not do what I needed it to do. Afraid I would lose all of my hard work as well as that of my wiki editors.
But my nuwiki was about to become unusable, so I was about to lose it anyway.
Vaultwiki did exactly what it said it would, and more. Yes, there was a learning curve and yes I had to do lots of tweaks for my own particular use. But it worked and I am very happy with my converted wiki and the vaultwiki capabilities.
A big thanks to pegasus for developing and continuing to work on this product and especially for the nuwiki converter!
