@mgol will the CLA company be publically visible? (have to clarify this before running it with our cla manager and sign the CLA)

[mgol]

@kkmuffme I don't know the answer to this question but I asked at the OpenJS Foundation, hopefully you'll get an answer.

[lukeschantz]

I asked some folks with experience with the CLA and here is the response "the only thing that is visible in the PR is whether or not the CLA check passed or failed (and, if it failed, which commit authors failed the check). So, no, it wouldn't be publicly visible."

Thanks, there's a bug awith EasyCLA atm and signing new CLAs doesn't work; waiting for their reply and fix (will be at least a week though from what I gathered)

@mgol ready to be merged
