Visibility and accessibility

[emilvincentz]

• [ ] It needs to be very clear, what the visiibilty and accessability is for the space or chat you are in. Like, can anyone join? can everyone see it but needs to be approved or is it hidden and invite only?
• [ ] We need figure out how users manage the visiblity and acccesability settings when they create a space or chat (maybe also event) and also how they modify it later on.

For spaces and chat we are bound by the matrix protocol, so would be good to look at element or other matrix clients to figture out how they do it.
