As we build our wiki there are Page Names? for details and there are related pages that are grouped under Chapter Names which is another word for the Sub Index. A Table Of Contents is another name for the Main Index.
This is an idea that there could be a use for indexes within indexes in larger wiki. I think that this could be needed in the Sola Roof group in a while. Or it could be useful to organize groups by type within the entire wiki. I am not certain about this idea. What do you think? We will become a community of communities - but with a common purpose to build a sustainable future.
