of course the date of installation is relevant for now, there is a week between emailing the users and actually deleting them
Your remark if i am correct was that they where not deleted: how could they have been deleted if not a week passed by ?
- you installed the ext on 22/11/2014
- there are users who are valid for auto-deletion, so they received an automated email
- when they do not respond, they get auto-deleted at 22 + 1 week /11/2014 => 29/11/2014
However, today is 26/11/2014 and you where expecting they where already deleted ?
I understand now from you answer that the users where not emailed ?
