This is my list of questions
Is there a way to change the page names once they are written?
How do I link to a different spot in the same page?
The general form for links is to enclose the tags with brackets: [[namespace:pagename#section|display text]] Any of those four things can be left off and a default will be chosen. The section is simply the name of the section on the page. If you start the link with the hash mark, so that it looks like this: [[#section]] it will point to that section on the same page.
Is there a size limit? Is there some sort of meter?
Do we scam this by linking rather than including things?
====== Will this header look like a sub bullet? ====== no
How do I change fonts, sizes, colors?
I just added font colors, size and font family to the editor, also background color. None of this works with headers I don't think. We need to experiment. It is possible to apply styles to sections as a whole too. Learning curve. Header size is determined by section choices.
