Right now (as of about August), we send an email to students who are registered via an LMS. This email says:
“[Professor Name] has registered you as a participant with their Poll Everywhere account. To log in and complete the registration process use the following link: [password_link]”

We’re currently working on a way to allow professors to resend this link to their students in bulk if they haven’t received it or haven’t logged in. We can definitely look into some ways to customize this message, but it is a bit larger of a project than we’d like because we need to store these customized messages, add some handling to prevent spam (in case someone is only pretending to be an educator), and then change the LMS invitation workflow to allow some handling to customize the email. It’s something we will definitely consider if we hear it requested from some other folks.

Otherwise, is there anything specifically that you would like added to the default message? We can edit the universal email easily if there is some information that you think would be particularly useful for you students

Thanks for the feedback!
