This is a nice concept, few months back I sat with a gang of people to try something like this using Google doc. I was helping them to edit on Wikipedia using a shared Google doc as a tutorial. I started posting few step by step procedure (e.g. How to create a new account, How to search, edit and save, How to add references, etc.). Every time someone was facing a problem in any step was asking me a question and I was answering the same thread. Have a look at the file for a sample.
I'd like to request you guys to post such a screenshot of the EtherEditor which would be easy to visualize.
