C. S. Wyatt has created a Wikibooks entry.  From his NUG post:

Now that I have created a Wikibook... it has a discussion page or we can discuss some matters here. I am hoping the project takes off and helps promote REALbasic. It\'s also a great place to share sample code!

Feel free to let me know how to best organize \"chapters\" of the book. here are Wikibook standards for programming guides, which I used as the basis for this empty book.

I think there should be an introduction on objects and methods, for example. A chapter on what is good \"cross platform\" habits, since UI 
standards vary, would also be nice.

Anyway, just wanted to give this project a swift kick in the pants.
