Microsoft Certified Professional (MCP) certificates are being issued digitally instead of printed and mailed.
While this is good news from a "go green" perspective, it's also good in that it allows new MCPs to access their cert more quickly, save it and send it to an employer as needed. Supposedly, the certificates will be accessible immediately after the completion of the exam.
If you still want the old piece of paper from Microsoft that represents an official certificate, don't worry -- you'll be able to order those beginning July 15 (this will entail shipping and handling charges, though).
