Hello

1. Is there any possibility to associate local users to groups ?

2. Is there any possibility to limit access per group ? For example, to be able to subscribe/post/comment only to local groups even the server is federated ?

3. Any possibility to automatically insert ads on local server on viewing anything ? Servers cost money and monetization is necessary since donation is just an occasional income.

4. Is it possible to limit federation only to a pre-defined list of internet domains and deny all the rest ?

Thanks.
