H!
Looks like this guy - https://moodle.org/plugins/mod_adaptivequiz - acquired a new maintainer (you won't believe it, it's me 😃 ), so I think it would make sense to remove it from the 'Seeking new maintainer' set. I'm also planning to contact Adam (the original plugin developer) to hand off the maintenance completely a bit later.
Let me know if I'm required to take any extra steps in this story, thank you!
