Hello,
How do I stop students from seeing other participants email addresses? - There must be an obvious solution but I've looked at everything that I can think of including the list of permissions....
Thanks,
Paul
By default Moodle assumes that you will be creating new user accounts, and skips records where the username matches an existing account. However, if you set "Update existing accounts" to Yes, the existing user account will be updated.
When updating existing accounts you can change usernames as well. Set "Allow renames" to Yes and include in your file a field called oldusername
.
Warning: any errors updating existing accounts can affect your users badly. Be careful when using the options to update.
