I don’t know about anyone else, but I’ve noticed that the unsubscribe button at the top of threads doesn’t do anything when I push it. I’m posting this here to find out if others have this problem, and if so to (a) suggest someone look into fixing it, and (b) point out a handy simple work around:
When I want to unsubscribe, I go to the checkbox under the “Post a reply” box, uncheck it, enter a single space into the text field, and hit “Post!” Nothing is posted, but the thread is unsubscribed.
