If you invited the user through email, you can select the “Resend Invite” button next to their email. When doing so, you also have the option to resend their invite to a different email address.
If you did not invite the user through email and only provided them with a user ID and temporary password, find out what user ID they were initially assigned and select their group. Scroll to the bottom to find a list of your pending invites and utilize the search function to find the temporary password associated with the user ID.
