Convert secret circle to private circle

Circles are a way you can create groups of people in Nextcloud to more easily share folders and calendars.

When creating a circle, you are given four some-what confusing choices about the kind of circle you want to create:

• Personal circle: a private circle that only the owner sees and can modify
• Public circle: a public circle all members can see and join
• Closed circle: a public circle that all members can see, but requires owner approval to join
• Secret circle: a private circle that is not listed publicly and does not show up in search results.

From this description, it seems that a secret circle is the way to go, since a secret circle is not visible to other members. However, if someone knows the full name of a secret circle they can join it without owner approval.

Unfortunately, ​this flaw seriously compromises the security of a secret circle and therefore we recommend that everyone convert your secret circles to personal circles. You can do so by taking the following steps:

• Create a new personal circle (you can use the same name as the correponding secret circle)
• Add the same users to the personal circle
• Share the folder or calendar currently shared with the secret circle to your new personal circle. When finished with this step, it will be shared to both circles.

• Unshare the folder or calendar with the secret circle

• Delete the secret circle
