App.net does not have built-in support for creating private groups in the same way that some other social networking platforms do. The platform primarily focuses on providing a space for users to share and communicate publicly. However, users can create posts that can be restricted to their followers or close connections, which can serve as a sort of private interaction within the platform.
For more extensive discussions or private collaborations, users might consider utilizing direct messages to communicate privately with other users. This allows for a more personal conversation without the need for public visibility. If you are looking for specific features or updates related to group functionalities, it is always a good idea to check the current web page for the latest information and any potential changes that may have been made.
