I am running Discourse for my classes at a school. I have invited all the students (via the bulk CSV upload utility) but would now like to bulk change all their usernames to be their real names (rather than their chosen pseudonyms) so everyone knows who they are talking to on the forum.
Their email addresses are their school email addresses, so I can use those as a primary key (of sorts) to change their usernames. Is there a way to do this, I am guessing through SSH on the command line?
Also, is there a way to then stop the users from changing their usernames back to something else?
