Hi Jay,
Create a process with SystemUser as ProcessInput.
The process will have 1 rule: LOGOUT SystemUser
You can then call this process from a Query of SystemUser that displays users.
I have a process which allows administrators to see who is online & log them out:
FIND SystemUser WHERE SystemUser.ID IS DEFINED IN BATCHES OF 1
DISPLAY 'Users Logged On Now'
Users have a rule:
If NMB_OF_SESSIONS(RegularUser)>0 Then
RegularUser.LoggedOnNow='Yes'
Else
RegularUser.LoggedOnNow='No'
