Users Delete themselves?

its not actually a problem but a question..

be4 3 days i received a email with the following msg:
"Hi,

You receive this automatic e-mail because -[Username]- on "******* Forum" - http://www.**********.com has deleted his account."

i think i have see an option in admin panel "Allow users to delete their accounts" but im not sure if it actually exist cause i have look for it but couldnt find it.. (or im blind xD)
also i made a test account and some of my members helped me with it and they dont see any option like this.

so how they do it?

Hi!

Users can delete themselves using this tool: https://www.forumotion.com/en/unscribe/

You can stop users from doing this at:

1. Administration Panel (advanced mode)
2. Users & Groups Tab
3. Users options (on the left, under Users)
4. Select 'Allow members to unsubscribe : No'
