I made the severe mistake of commenting on a free T-shirt thread. Now I keep getting notifications.
How to Unsubscribe/Unfollow the thread?
On the top of the post, under Options, Subscribe/Unsubscribe.
Unfortunately, I only see a subscribe button.
Try going to your profile (your avatar in the upper right), My Settings, Subscriptions, and then check the ones you want to remove and select Delete/Remove.
A post I'm getting notifications on does not show I'm subscribed. In that same spot where "unsubscribe" is shown, it says "subscribe". Yet I am still getting notices of responses.
I think you have to push subscribe first, then unsubscribe. Then it works.
