Just JUNK that may be DELETED, at any time
Purpose:
Its purpose is multi-, as follows:
- A basic understanding of the syntax, structure, capabilities and limitations of Wiki editing.
- Attempts to mix Wiki-style and HTML-style editing (The former is new to me; the latter I am not fond of.)
- I'd PREFER to fully edit off-line, and port to the proper pages,
- Gain an understanding of the implementation of the "wiki-style" pages.
