You need to set up server/vault first (can do on the same machine or a different machine). Then you would have to connect to the server to run the client (WPDM) on your machine.
What kind of file history you had been using?
Tom,... I have to ask cuz I'm curious (hand raised)... at university level,.. why would you care to take the time or place any energy into finding out if a student is/are/were cheating. Would they not be cheating themselves.. since they are paying for the education... or is it a policy to check on grant/scholarship students only?
