Yes! I'm the organizer and we will get the auto-invite domain back online at some point. Life has gotten in the way... Thank you for sharing the link in the meantime. You can also email me and I'll send an invite.

It's a friendly group of nerds and entrepreneurs. We'll do another in-person event as soon as we can! You can sign up on doorkeeper if you want an announcement email when it goes live: https://manage.doorkeeper.jp/groups/hntokyo
