A minor interjection into this discussion: "if .. else if .." is supported in the beta.

Was there a request in the original tutorial that credit should be given for derivative works?

It is very common for C++ developers to get code snippets or code inspirations from CodeGuru. It is generally not specified that any credit should be given because it is understood that there is a free exchange of code on that site. Sometimes a request for credit is made.

I suspect that many many people have based preloaders or dynamic text scroll bars on code obtained from Flash tutorials without giving credit and probably no credit was expected.
