Be aware that our Blackboard Learn Environment (http://pavcs.blackboard.com) will be unavailable for July 23rd due to schuduled software upgrades. The downtime will begin at 6:30am and will continue until 6:30pm. After the software upgrade, you may find that Blackboard does not look the same as you are used to. It could take a day or two to re-apply all settings/styles/etc. We ask that you hold off until after Wed (July 26th) before submiting any tech support requests.

The email is really sent from a friend's email account, because his/her account was comprimised, and was used to send the email to you.
With today's scam, and the larger one just over 2 weeks ago, the PA Virtual Technology Department hightly suggests that everyone takes a few minutes to review the How To Spot Dangerous Emails FAQ page.
