This Plugin adds a widget with a user recognition game. In a configurable time interval, the avatar of a random user is shown to each logged-in visitor of your site. The visitor will have a configurable number of choices of registered user names on your site. The visitor can pick one choice and will be informed of he/she was right or wrong. This plugin is integrated with <a href="https://wordpress.org/extend/plugins/badgeos/" title="BadgeOS" rel="ugc">BadgeOS</a> as it addes triggers to be used as achievement steps. Furthermore it integrates with <a href="https://wordpress.org/extend/plugins/buddypress/" title="BuddyPress" rel="ugc">BuddyPress</a> as it links the users avatar with his/her profile page on completion of the game. Neither of both plugins are requirements though.
This plugin was originally developed for the <a href="https://quality4digitallearning.org/" rel="nofollow ugc">globe – Community of Digital Learning</a> on behalf of <a href="https://www.giz.de/" rel="nofollow ugc">GIZ</a>.
