Are these nodes dedicated servers (aka sitting in a rack) or 
non-dedicated desktops (aka cycle scavenging) ?

If they are dedicated nodes, then change your START expression to be

START = ( (User == "userfoo@xxxxxxx") || \
          (User == "userbar@xxxxxxx") )

substituting the userids as appropriate and do not worry about load 
average or keyboard.

Look at an example job from a workshop owner, and confirm that the 
"User" attribute is what you placed in the START expression above.  For 
instance, if job 55.0 is from a workshop user, do
   condor_q -l 55.0
and confirm you have an attribute for that job that matches an entry in 
your START expression, eg
   User == "userfoo@xxxxxxx"
You could also try "condor_q -analyze 55.0"

Don't forget to do a condor_reconfig or restart the Condor service on 
the execute nodes you changed...

Todd
