Archiving
You can ask for archiving your Moodle base for further use. This will make it invisible for the students. Request for this procedure is done via email to esamk.tuki@samk.fi
If you are totally certain you will never ever need the base in question in the future you can ask for it’s removal. Please notice that this is a procedure that cannot be undone!
