I joined today but if I want to unsubscribe, how can I do that since I don't see it in the Help section.

Thank you!

click on user profile ->left side of link bar

in the left pane go down to subscriptions

select all

drop down bar go to delete subscriptions

There is no option to delete your account if that's what you are asking for. We mass delete inactive accounts after a while and there is no reason for you to receive emails from us if you are not active, so don't worry.
