Now I realize that my choice of editor is a big problem to collaborate, so I am thinking of another approach.
As the most important is the content, it may be more operative to create a wiki so that we can all collaborate more easily. Then I will pass everything to pdf.
I will start a Tiddlywiki with all chapters, drawings etc. But, tell me please: What platform do we have to choose to make collaboration easier?
This week I will pass everything I already have in Lyx to a wiki.. This will be a big effort, but I want this book to be everyone's job.
Thanks!!
This support gives me a lot of energy to continue with the project
