We have now changed the Teachers page to allow you to both add students or update existing user account information. When you click to manage you students, you will get a table with existing accounts displayed (passwords and emails will be hidden) and any spare slots also listed for adding new accounts. You can now update emails and passwords for existing ones (or leave alone if you wish) as well as add new accounts, all from the same table.
Yell if it doesn't work. And don't forget that if you have an existing account, it will be listed with email and password info as '********'. You don't need to touch this if you don't want to change it - it wont really update the account with asterisks
