I was not sure what to do and I was expecting a more clever answer from the community than my 4th / worst proposal (= removing the “text link”) .
Ok I won’t hesitate to edit any documentation page (see also) … after all it’s a wiki .
This raised a question: How do community moderates documentation changes?
For instance I have noticed a page with 9 attachments which are note used in the page (see : https://www.xwiki.org/xwiki/bin/view/Documentation/AdminGuide/Access%20Rights/Permission%20types/). Contrary to my “prudent” behaviour which leads to this original post, there I have directly removed attachements … but does someone will check I haven’t done any mistake?
