While digging through [mediawiki] I noticed some questions which are about using some specific wiki (such as Does the German Wiktionary have a way to request words to be added? which I don't think should be tagged
mediawiki because it has nothing to do with the software) whilst most questions are more about configuring the software itself (like https://webapps.stackexchange.com/questions/15682/mediawiki-deny-article-edit-right-to-all-users-except-admin-and-article-owner). This configuration issues clearly seem off-topic for me. Some seem borderline cases for me such as How can I float the table of contents to the right with MediaWiki (if it should be on-topic it clearly deserves the
mediawiki tag because it is a general question how to use the web interface of this software and may even help non-administrators in using it).
How should we deal with these questions?
