Guess this is the houzz version of gardenweb now.

As for the emails, at the top right of the page it says "your houzz" click on that and go to your settings, there you can change all sorts of things...

For each notification you receive for a new comment, you can also turn off notifications for just that discussion by looking for two links at the bottom of the email. One will turn them off for just that thread, the other will turn them off for all threads. Hope that helps!
