vExpert 2014

For those unknown with the term: “vExpert” is not a technical certification or a general measure of VMware expertise. The annual VMware vExpert title is given to individuals who have significantly contributed to the community of VMware users over the past year. The title is awarded to individuals (not employers) for their commitment to sharing their knowledge and passion for VMware technology above and beyond their job requirements. Here is the complete list of vExperts 2014.

If you feel you have contributed to the VMware community and did not apply for vExpert, good news.. the Q2 applications are already open at http://www.jotformpro.com/form/40285638168967. Good luck!
