Hi @andrastia PUM is fun, it forces you to be a bit more disciplined and for me it is what for me addicted to hive. My first four months I was hardly here, but January1st this year a couple of friends persuaded me to do the PUD and PUM and I have not looked back.
As for the community engagement, this is a social site, which to me means not surprisingly being social and engaging. Me thinks you know the topics already 😁
