I know this question has been asked previously but I don't seem to be able to find an answer to my specific question. I tried following the link but it is dead. I have deleted several test users by deleting the master account thinking it would delete all information. I now have several user names and emails that are no longer available because they have been used. Two things: what is the proper way to delete a user account and what can I do to finish deleting the information that remains from the already deleted user accounts? thanks in advance.
