Flexwikers,
The Flexwiki.pm in my last email has, in the handling of local href
links, hardcoded "[PlayPage]" where it should have something like
"[<currentPageName>] which I don't know how to do yet. So links on a
page to local anchors will not work unless you edit PlayPage in the
output HTML to be the name of the page in question. I will post the
code again when I've changed that and added other new rule material.
