Wiki Syntax spread over three places
1. When editing a Wiki page the very useful (but not complete enough)
Wiki Syntax reference can be seen when clicking on "Text formatting:
Help" (called Wiki Syntax Quick Reference).
2. So at the bottom of this Reference is "More information" that goes
to https://www.ohwr.org/help/wiki_syntax_detailed.html (Wiki
Formatting). Userful, but again this one is not complete.
3. The final place where I can find useful info as Horizontal
seperators, Disabling text formatting, and more details about linking
and images, can be found via OHR Support -> Getting Started -> User
Guide. In fact this user guide is not an OHWR User guide (which is
suggestsed), but it's called "Complete guide for wiki editing" (which it
defintely isn't):
https://www.ohwr.org/project/ohr-support/wikis/User_guide
Please do some cleaning up, or, as a quick patch, at least make link 3 also available from the first page mentioned above.
