some time ago I saw on this list an GET option, which causes the output of the wiki text instead of the rendered version. Since I cannot remember how it was named, can someone please tell me?
Some thing like "&export=wiki" or "&feed=plain" or...
Wiki pages have a footer "Download in other formats / Plain text" and the plain text is a link to the wiki page with "?format=txt". Is that what you're talking about?
