Diaspora/Diaspora

No, it is not possible to reshare any private post. This is to respect the intentions of the original poster, who shared it only with a particular group of people.

What happens when I add someone to one of my aspects, or when someone adds me to one of their aspects?

Let’s say that Amy adds Ben to an aspect, but Ben has not (yet) added Amy to an aspect:

Ben will receive a notification that Amy has “started sharing” with Ben.

Amy will start to see Ben’s public posts in her stream.

Amy will not see any of Ben’s private posts.

Ben will not see Amy’s public or private posts in his stream.

But if Ben goes to Amy’s profile page, then he will see the private posts that Amy makes to the aspect that she has placed him in (as well as her public posts, which anyone can see there).

Ben will be able to see Amy’s private profile (biography, location, gender, birthday).

Amy will appear under “Only sharing with me” on Ben’s contacts page.

This is known as asymmetrical sharing. If and when Ben also adds Amy to an aspect then it would become mutual sharing, with both Amy’s and Ben’s public posts and relevant private posts appearing in each other’s streams, and Amy would be able to view Ben’s private profile. They would then also be able to send each other private messages.

Who are the people listed under “Only sharing with me” on my contacts page?

These are people that have added you to one of their aspects, but who are not (yet) in any of your aspects. In other words, they are sharing with you, but you are not sharing with them: you can think of this as them “following” you. If you add them to an aspect, they will then appear under that aspect and not under “Only sharing with me”. See above.

Is there a list of people whom I have added to one of my aspects, but who have not added me to one of theirs?

No, but you can see whether or not someone is sharing with you by visiting their profile page. If they are, there will be a green tick next to their diaspora* ID. If they are not, there will be a gray circle.

When I add someone to an aspect, can they see older posts that I have already posted to that aspect?

No. They will only be able to see new posts to that aspect. They (and everyone else) can see your older public posts on your profile page, and they may also see them in their stream.
