Hi reggie, you can change and choose notifications under Your Houzz, Edit Profile, Advanced Settings

Amy, thank you for responding! I knew I'm not crazy, that there had to be that option. I can't find 'edit profile'. Pls clarify again where in Your Houzz I can find that field. Thanks!!!

In the top right corner of your Houzz page it will say "YOUR HOUZZ" in bold letters. Hold your mouse over that and it will pull out a drop down menu. The first green link is labeled "Edit Profile." Click on that. It will take you to your profile. Scroll all the way to the bottom. Click on "Advanced Settings" and there will be a list of check marks. Click which you would like to receive notifications on and then save the changes. ^_^

Also, if you visit your profile via the Houzz website, you can see all the discussions you have participated in there.

Thank you all; I appreciate your patience. I couldn't seem to do it from my iPad, I needed my desktop. All done.
