Right now there's no integration- it's a totally separate coin community doing cool stuff hopping over and trying out Hive social media. Integrations, cross building, logins and other things may be in the future, but both ecosystems are fully staffed by volunteers who just build things they love because it's great. We may have tools to offer them, and our peeps may love their PoW private, fast coin~ but they want a home base to have a forum, and a Hive based community is a great place to do that :) so here they are!
