Wikitech-l, Opinion polling and voting can be utilized in talk pages and throughout the various administrative and bureaucratic processes of wiki communities. Opinion polling and voting are available for MediaWiki through a number of extensions. A popular one is SecurePoll which has been “used for Wikimedia Foundation Board elections and arbitration committee elections, and was used for the Wikimedia license transition vote among other things” (https://www.mediawiki.org/wiki/Extension:SecurePoll). I recently read about an interesting software, Vocdoni (https://vocdoni.io/ , https://vocdoni.io/docs/#/), which utilizes peer-to-peer technology and blockchain to provide opinion polling and voting. Perhaps there will, one day, be MediaWiki extensions for interoperation with such systems. Best regards, Adam Sobieski
