I subscribed to a post years ago, and I have been getting notifications lately.  The email notification said that I needed to go to the post and click "unsubscribe".  I can't find an unsubscribe button.  I asked the "Help" bot, and it was clueless.  When they redid the website, did they forget to include that option?  Who do I speak to about this?

Nevermind; I found it.  I had to click on the yellow star in the top left with the word "Subscribed" below it.  I think that it is automatic when you start a thread.
