I think the forum is broken. If I click the link in "To unsubscribe, click here" link, which for me points to a 404 page. How do I unsubscribe from emails I don't want? See this video (obscured left side for privacy):
Just found this setting under preferences; hopefully this works. In the meantime, I think there's a bug that needs to be fixed in your email notification system.
Thank you for reporting this! The issue was the lack of an appropriate redirect for the unsubscribe links (as we changed the forums from community.leapmotion.com to forums.leapmotion.com). The issue has been resolved.
