Yeah the DarkGDK.Net stuff is pretty light on the tutorials. There are 6 of them (including a few legacy ones), but they don't cover a ton of stuff, I think. The CHM help file is pretty good, though what is wrong with that?
DBPro didn't come with many tutorials, either. In fact when I bought it, it came with ONE in the manual.
I think DarkGDK.Net was written by one person. If you're expecting the level of community support of XNA who has thousands of users and countless developers... well, you're just going to get disappointed.
Forums don't have much because I don't think a ton of people have gotten DarkGDK.Net yet, it just came out. There are a few power users who are saavy with it already but they don't always answer every question in a timely manner. They're not paid for support, they're users just like you and me.
Sorry your 2 previous questions went unanswered so far but sometimes it's good to learn by just writing lots of code and trying out new things.
Another approach to your dilemma is to just plod forward with your project and learn as much as you can about the framework. Pretty soon you'll be a power user, who can help other users when they complain about the lack of tutorials.
I'm not a real programmer but I play one with DBPro!
