Receiving a lot of non subscribed notifications

[tapi]

I am receiving notification emails for every post from every topic of the section "Input and output". In the past, I may have subscribed this whole section for a while but now it is certainly not in the list of my active subscriptions (I checked it) buy yet I am receiving notifications of "input and output" from the new forum since it's introduction a few days ago.

To forum admin: would you pls cancel this particular bunch of notifications for me? Thank you.
