Some of you have asked about the privacy of posts. This is what HU says in their admin info:
"Defining who can view your posts or questions:
Just like you can make certain information in your profile private, there is a similar feature with regards to your posts and questions.
When submitting a post or question you have the choice between making it visible to Everyone or to Members of this community only.
Everyone means that the post/question along with the replies can be seen by both members of that community as well as visitors (whether they are HealthUnlocked members or not).
Members of this community only means that the visibility of the post/question is strictly limited to just the title and the first 247 characters for anyone who is just a visitor (whether they are HealthUnlocked members or not) while only members of the community can see the author's username as well as the full post/question and replies."
