I would like to unsubscribe from one SevenForums thread. I get notifications of new postings to that thread by email, along with a link that says, 'To unsubscribe from this thread, please visit this page:' [and the url].
But when I click it (or copy and paste into the address bar), I get a page saying 'An invalid threadid or forumid was specified.'
I can't find any other way to unsubscribe from just one thread (I want to keep my others alive). Could someone please tell me how to do it?
