Bodz, I see you are already set to auto subscribe without notification so not sure why you are getting email notices to subscribed threads.
Here's a direct link to the edit options
Here's more detail. The way to check this and edit your options is ...
- Go to UserCP (in green menu bar above)
- Find Settings and Options (on the left side of your screen)
- Find Edit Options
- Scroll down to Messaging and Notifications
- Edit Default Thread Subscription Mode to "No Email Notification", which will subscribe so you can check threads in the quick links subscriptions but without notification by email or "Do Not Subscribe", which means no subscriptions and no notifications.
Also click off email notices of new PMs.
Let me know if this helps.
