The new Dynamics NAV Test Drive site has been released! You can find it here: http://www.dynamicsnavtestdrive.com/
This first release of the update will be updated again in a month or two with more content, especially more ISV DemoMate demos (from CfMD solution partners).
This demo site allows people to log into Dynamics NAV then by following instructions, do such things as customising the role centre or personalising a sales order.
Check it out!
