 Okay, let's go about a bulk upload of users. So your login is the site administrator. Got it the site admin block, users, accounts, upload users. Now I'm presuming you've got the text file or the spreadsheet file saved in CSV, comma separated value format ready to go and the convention is right. So what you then do is choose the file and upload the users. It'll pre-process the records here. We can see them up at the top. We've in fact got two new users and an existing user whose records we simply want to update. But we're mindful that there's a password in the system. We don't want to change that for this user. Okay, there's the five mandatory fields there. You can see username, password, first name, last name, email address. And if you put change me as the password, that will force the user to change their password upon first login. Okay, so those three records are ready to be processed. That's the preview. So the upload type in this case will be add new, update existing. What we want to do with, well say with new users, the password is required, in this case, that's a required field in the file. With existing user details, so that's in fact the third record in that preview, we want to override with the file. The important thing though is with the existing password for this user, we want to leave it as it is in the system and not update that. So we say no changes. Now I'll leave the rest as defaults, there's a lot more you can do down here with the settings and certainly with default values for the users that you are bulk uploading and creating. Upload users. So that has done that for us now. Two users been created, one user was updated and you can see the existing user's record was updated there, the email address was in fact changed but the existing password would have been preserved. So that's it, that's all that's involved with a bulk upload naturally tested on a small file first with a few students before you commit that to hundreds of thousands.
