thx so much!!!! :)

I am having the same problem. my new ideabooks are showing up Public and the collaborate button is missing... no answer from houzz

any response?

This went to my junk mail and I just found it. My existing Idea books are “Private” and I just happened to notice my new ones were Public. Very frustrating trying to change. I imagine this is not a priority.

As I said in my first comment above, I believe you can make ALL your ideabooks private if you go to "Edit profile" and click advanced settings. I haven't tried it since I want to keep mine public. I think you can just uncheck the top box:

Thx Groveraxle I will take a look at that! This is usually a weekend thing for me. Susan

Thank you Im having the same problem ... thought I was going mad ! but your comments have been very helpful. Ive unticked the top box @groveraxle !
