Yes, it possible co create tutorial page, something similar like gootool has. XDBoy wrote a good tutorial a long time ago, I'm going to publish it how but I don't have much time to update it to 0.66 editor

There can be a flash movie.I'm experienced with flash.I can make a book with pages.

@Joris
We already have the pages for the editor, we just need a good tutorial. You could make some flash animations but I don't see you can I use them here

@Daft as Brush
Well, it isn't easy as I imagined. I did add it as a 'book page' to 'Developers' but it look like it impossible for moderators to add it to the drop down menu of Developers, we need davidc for that one.

For now, it is only accsasable by clicking "Developers" button from the top menu.

If you like me to put it somewhere else like in World of Goo page just name it

So, XDBoy wrote About WOG Editor, witch is now the main page of it named 'WOG Editor', he wrote the Basics and he started writing on 'Simple goo ball modding' and 'Learning how to goomod' while 'Making of... a Level' is just copied form http://sourceforge.net.... by me to fill out the blank page.

So, feel free to add or change anything that you don't like, you just have to send me the text via email or post it here

I think it's OK where it is...
I'll drop direct links to the page in the software and on my WoG editor page... should be enough for now.

A lot of it looks OK, but there's quite a bit that's "out-of-date" now.
Is there a way you can grant me editing rights or transfer ownership of the pages to me? So I can change them myself, if I promise to credit XDBoy!

That would be easier... but if it's impossible... then... OK!

Was thinking the same but I'm not sure. I'll transfer author rights to you now...

EDIT: done! so....?

Close... but no cigar!
The tracker now shows me as the Author... great!

BUT...
They don't appear in My Account (not sure if they should?)
And if I view the pages themselves I don't see any way to edit them...
I was maybe expecting the View / Edit tabs like my add-in pages.

Is there something I'm missing... or maybe something you've missed?

EDIT:
I think you need to make me a "Contributor"... if you can.
http://goofans.com/goofans/contributors says at the bottom "ask for editing access"

No, I'm not missing anything, I wasn't expecting this to work, was hoping that you will see view and edit tabs like in your addins but no luck.
I can't make you a contributor, only davidc can.
So, for now, we wait for davidc or you can send me the pages of the editor tutorial.
Sorry

Ah well...
Should I shoot him an email, instead of waiting for him to notice this thread?

In the meantime I'll grab all the original HTML and get editing!

Oh.. and you did miss something..
"Making of... a Level" http://goofans.com/developers/about-wog-editor/making-of-level
is still under XDBoy.
