Unsubscribing from an unsubscribed thread

[#1]

How do I do it? As strange as the question may seem, I am still getting notification via email and a listing on 'Replies to your post' for a thread that is not listed on my subscriptions list. I tried subscribing once again, so that I could remove it again, but I'm still getting the notifications and it's annoying the hell out of me.

Hello Jim.  It's http://community.plus.net/forum/index.php/topic,109017.0.html

As you say you aren't subscribed to it.
If it happens again it will need a staff admin to investigate as I don't have the necessary permissions

OK, thanks for looking at it, nonetheless.
