Hello. My username is Mark at Alcoa (talk) and from 2007 to 2014 I was a member of Alcoa's corporate communications team. I selected this username to promote transparency in my active participation in the Alcoa article within rules, policies and COI guidelines. As a connected contributor, I expected and welcomed open and honest dialogue and collaboration around any edits I made, or edits I suggested on Alcoa's Talk page, past or present. For full disclosure, I was not authorized nor did I purport to speak or edit on behalf of the company. The edits and actions therein were mine alone. I left Alcoa in August 2014.
