Textpattern CMS support forum
I just looked, and I have been a member of the Textpattern forum for 18 years. Here is my first ever plugin.
daz_clickable_keywords is a drop-in replacement for <txp:keywords />, except it makes each keyword clickable as a link.
Pair it with <txp:article_custom keywords=’<txp:page_url type=“keyword” />’ /> and you have got yourself a list of all articles with that keyword.
