What do you know about batch uploading users?

• You should read up on this first at Moodle Docs http://docs.moodle.org/en/Upload_users
• You can use a template like this one  moodleimport.csv.
• Fieldnames on the template are those requested by Moodle and should not be changed.
• Once the upload is finished, Moodle should give you a report on the number of users added and any errors encountered.
