I hut realized that all new posts on google plus are shared with “community” and not public! This means if you are not part of the community you will not be able to see the posts 
Anyone know if there is a way to modify existing post to make them public? I was only able to reshare and make public but not modify old posts.
@ Gus - looks like you are going to have to re post. I just tried to edit one of my posts and no joy, I can only edit the text (ipad google app)
If I get a chance I will look a bit deeper. Might be able to do it on the plus site.
I think you can click on the arrow “Share this post” near “+1” and you can modify the share.
That actually creates another post
Posting to the public means? The whole world? That would be super-spam.
