I am uploading my students as an CSV file using moodle 2.3. Under 'maildisplay' I have 'Hide my email address from other users'. Everytime I add this field and try to upload I get an 'Error writing to database' message. I've tried a number of things already: moving the field to a different column in the spreadheet and a number of other things. What gives?
If I can get this to work it will be much easier than having my students hide their addresses themselves.
Any advice would be appreciated.
