I just wanted to check with you whether you want to make it public, as per the discussion https://discourse.llvm.org/t/hidden-emails-on-github-should-we-do-something-about-it/74223/67. AFAICT there's still no official policy, but thought I'd check.

I was not aware my email was private. It should be public now. Thanks
