A few facts and figures...
As you may know, the KLZ has been going strong now for a couple of months. In that time we have processed over 93,000 e-mail messages and almost 16000 Sharepoint items. There are over 40 schools on the system and over 3500 active school users.
Behind the scenes, amongst our other infratructure servers, we have 7 Exchange Servers and 6 SharePoint Servers happily chugging away!
