Hello all, thanks for responding via e-mail, I am now on the list, just didn't have the time to do this before.
I think the optimal solution is the Tcl/Tk script, I cannot set the uid for a shutdown because the room is "open access" and the last thing I want is a bunch of students playing tricks on each other. Thanks to all for helping, Ciao, Arrigo -- Arrigo Triulzi <[EMAIL PROTECTED]>, http://www.ma.ic.ac.uk/~agbt Mathematics Dept.
