I started with Bryce 4, the boxed version, and read the manual and did the tuts within. I also have the Kitchen book which has turned out to be the best book buy I have ever purchased. I went from Bryce 4 to 5 and then 5.5 and now have 6.1.

I have learned the new features of later versions by just trying them out and seeing what happens. And also by consulting online tuts and pdf's. But I haven't used DAZ's much. Mostly going to 3dcommune and Peter Sharp's website and also Brycetech. I much prefer written tuts with photos and screen shots over video tuts.

The forum here is also a great place to learn new tricks. The people here are very knowledgeable and always willing to help. The atmosphere is friendly (well, most of the time) and laidback and I don't feel intimidated to join in on a thread whenever I have something to contribute.
