PLEASE TAKE NOTE - THIS IS THE THIRD TIME I HAVE ASKED FOR UNSUBSCRIBE
The email address lwal...@bluechiptechnology.co.uk nneds to be deleted
urgently. This is a former employee, I have to monitor this email box and it
is full of this beagleboard messaging which is no longer relevant to this
business.;
PLEASE ACTION URGENTLY
