You put macros into a page header, body, or footer text field. The macro syntax is [<=macroName] and for the forum plugin just put [<=forumList] in the body of a document. The FAQ browser is [<=faqBrowser] and it's usually in the header of a document.
(All of these are shown as examples and for testing in the development profile mock data.)
Thank you Christian!
It works perfectly, and I have to compliment you on fantastic work done on this WIKI software!
