I am getting a ton of emails and I don't want to get any more of them.
How do I make them stop, FOR JUST ONE THREAD. Not entirely.
You can't unfollow a thread. This is one of the annoying issues on this forum. I personally have disabled all email from the forum.
What I suggest is setting email for only private messages (which seldom happens) and on bookmarked threads.
If you post a question or are interested in a given thread, bookmark it.
Then when you aren't interested in it any more you can just un-bookmark it.
