how we can make the users able to deactivate or delete their accounts?
Hello there @Jay91!
The user can self-delete account if:
1 post or less
their account is less than a few days old
This setting kicks in on post number 2. You can self-delete if you have 0 or 1 posts. This self-delete option is right at the bottom of their user preferences page.
If you are forum admin, you may change this setting via
delete user max post age.
Hope this helped
