Can I hide my Posts to forums on my public profile page?
It's fine having it on my locked 'My Home' page. If they find my page I don't want just anyone to see my questions. They can search the forums if they need a answer to something I might or might not have asked.
Can I have some privacy at all?
I'm scrambling now trying to make myself more anonymous because of this.
Just click the little "minus" sign in the upper right-hand corner of your posts widget. That'll close it so that the posts can't be seen on your profile page.
