Thanks so much Rhonda! I see the comment I want to delete 3 posts down. When I hover over it, while in admin mode, I see no icons whatsoever on the comment. Perhaps we haven't earned editing rights yet, being so new to this site? (we have yet to add badges and referrals for a complete profile) In any event, we're in touch w/Help at Houzz and they told me this: "Just a note, when you create a thread and/or comment you will have to get support to have them removed." I have them working on deleting it for me for now. ...I think?!? :-)
Thanks again for taking time to give guidance. Have a great weekend!!

Hmmmm, suggest you write to support@houzz.com

Hi guys, You should see the option to edit or delete your own posts if you hover over them, but I have heard that sometimes they will not appear in some older browsers. Can you tell us what browser and version you are currently using? If you are not updated to current versions, be sure to do that as well.

I just noticed that on this page I can see and use the editing tools. I just deleted my previous comment. However, those tools do not appear on my profile page! Do you know why that is? ...strange. :-)

They only appear when you are viewing the discussion page, but that's good feedback that you would want to use it from your profile. Glad you found it!

Log into your account and go to your home page (idea book, messages, ACTIVITY. Click activity and if it's recent it will let you delete here. Otherwise, if the comment is old, it won't.
