If I create a blog post here, can it be viewed by everyone or only by people who are members of whatever space I post it in?
In other words, I have created a blog post Create visually appealing, automated dashboards using Klipfoliobut I don't think it is publicly visible?
I think you're supposed to have earned the "Blogging Rights" badge (though the post is probably still subject to moderation).
If it helps, when I click on the link it tells me that it's part of a private group (Sydney User Group). So it's possible that your user group members can see it, but not anyone outside the group.
