for some reason i started getting email notifications on just about every post in the after effects forum starting yesterday.
i checked my profile settings, and the notification state is set to 'none', and i don't think that i had accidentally clicked the 'email me when someone responds' option... but even if i had, i seem to be getting emails for posts i haven't read yet nor responded to.
This is a leader setting thing. I've unsubscribed you from receiving email as a leader of the AE forum. Many leaders want to be notified of emails in each forum they host, some don't. You start receiving them yesterday because of few of the leaders email addresses were broken and were fixed yesterday.
