Thanks for the feedback, and sorry about the extra emails. Replying to a thread used to subscribe you to it automatically, which wasn't what many of you wanted. That has changed:
- Replying no longer subscribes you. There's now a Subscribe to this thread box on the reply form, and it's unticked by default. If you're already subscribed to a thread, the box doesn't appear.
- Starting a thread still subscribes you, so you hear about the answers. The box on the new thread form starts ticked, and you can untick it before posting if you'd rather not.
- Want replies to subscribe you automatically? In Account Settings (under your avatar), open the Settings tab and use Subscribe When I Reply. That sets the starting state of the box on the reply form, and you can still change it on each post.
Threads you were already subscribed to stay as they were, so you may want to clear some out:
- Go to Account Settings → Subscriptions. You can tick several threads and use Unsubscribe selected, or use Unsubscribe from all threads to start fresh.
- Under Account Settings → Settings you can also switch thread emails off completely, or choose a daily or weekly digest instead of an email for every reply.
Let me know if anything isn't working the way you'd expect.
