I'm in the process of migrating my personal projects to Tangled! But, I've been unable to associate my commits with my Tangled user due to being unable to use the GitHub generated email. I believe the + sign trips up the validation. Here's an example: 740416+gm112@users.noreply.github.com
p.s. Love the project and what its trying to do! Its been great migrating over so far!
