Covered under my employment by IBM. I've set the author email on my commits to my IBM address, and I can be reached there for validation reasons if necessary. My Github user is also a member of the IBM Github organization.

@robilad : Apologies for the direct invoke, but I've seen you facilitate this process before, so hope this is still the right way to bump things:

I've waited a "few business days" but have seen no movement on the OCA verification, and have noticed no verification email inbound to me (chris.w.dennis at ibm.com).
