On behalf of the entire OSIsoft vCampus team, I am pleased to welcome Han Yong Lee to the team! You might have seen some of his posts already, but we didn't really announce his transition... until now
You can read more about Hang Yong on his profile (and why not update yours at the same time? Simply click on "Hello <Your Name>" and then click "Edit my profile")
Also make sure you can look out for posts by Han Yong on his personal blog... I know he's preparing a great post on how the new release of the PI Server (v3.4.380) performs better than previous versions of PI - don't miss that one!
