Questions about Clubhouse.

Hi guys. I hope everything is going well. So, I have been wanting to try out this app for awhile as I have had it on my phone for a few months now. However, I have some questions. First of all, is there a way to set it so that the first person who enters your room is not allowed to speak unless you tell them? I don’t really like the idea of the app putting the first person who joins the room on the stage automatically. Is there a way to change this? Also, is there the ability to message someone privately? Lastly, I will share my profile here. Please would you give me a follow if you don’t mind? Thanks.
