How to add a class of students so they can access and edit your wiki:

Add accounts with the User Creator tool (K–12 and Super wikis only)

If you are a teacher and need to add a whole class’ worth of student accounts, you can do it all at once by going to Manage Wiki > User Creator. You will be able to make accounts for all of your students, even if they don’t have email addresses.

Keep in mind that every Wikispaces username must be unique. Try using numbers, or initials, or a first name-last name combination to create unique usernames.
