XenForo [Liam W] (RIP) Member Self Delete (v2.0.5) Patch Level 3

This add-on gives your members the ability to delete their own accounts.
You have the option of setting a ‘cool down period’, during which time access to the board is restricted to a notice that their account is scheduled for deletion – they can cancel deletion before the cool down period ends.
Users are logged out when requesting deletion, and an email confirming them of their decision is sent.
