Ok, that's enough for me. In no way have I the intention of verbatim copy or
reuse sections of your application. I just wanted to know that it is ok to
use the ideas and techniques. They are very useful because it is very hard
to find examples in the net about, for example, how to do a login system or
how to integrate with GOODS in a full app. Of course, that is just a way to
do it, but an implementation shows you not only a working example about how
to solve a particular problem but also it opens your mind about the ways you
could do it in a different way without using the original code. It is a sort
of bootstrap for your app. That way you can begin your app and concentrate
in your app's very own functionality and later, when you feel more
confortable or have more experience, you can return to the code and recode
it in a different way, in your own style and with better integration to your
app. In fact that kind of development style is encouraged by Smalltalk.

Yeah, that is the way almost all understand it. The text is copyrighted.

I hope you can reach an agreement where the text is copyrighted but the code
is available to anyone (MIT license or public domain) because:
1. It would reach a wider audience
2. It would be most useful to people learning Seaside
3. It would help to promote Seaside (something we all here want)
4. It should be in the spirit of the academy, with the learning and
knowledge diffusion as the foremost objective.

Yes, a lot, thank you.
