Go into your profile; click on the 'Activity' bar. Once the Activity screen opens, there is a further menu choice on the far left that lists "Posts you Started". Clicking on that should produce your entire history of started threads, from the most recent to the oldest.

TBH, I don't know how far back it goes. I've been here 25years, give or take, but have never gone back that far. But it will certainty reflect what posts you have started in the last year or two.

Yes, that works.

The search engine here is bizarre now, think it is oriented towards threads that lead to ads or contractors. Sometimes you can sort of find the subject, but often just leads to colors of paint and design terms.

thanks gardengal48 - it worked but I could only see back to Sept 2021, I have many posts from last year I cannot see.

Try using Google and your account name plus "houzz"

Strange; I can see posts I've started all the way back to 2006, and apparently all of my comments.
