[Condor-users] Only run when logged of?

[Dave STREET <davey_street@xxxxxxxxxxx>]

I am sure this is easy and I know some people do it, but how can I make it so windows machines only accept jobs and run jobs while no one is logged on, and remove jobs as soon as a user logs in? 

I can see how to set up for CPU and keyboard busy. But I want to have the logged on status of the machine control when jobs can and cant run? 

Cheers
