What's a restricted channel?

#RestrictedChannels allow open discovery, search on the network and via search engines, SEO, sampling of the content while protecting the actual content.

1. Restricted Channels are publicly listed on the Network and are searchable & shareable.
2. Restricted Channels can be opened by anyone, and the channel details and feed cards can be viewed.
3. Content from Restricted Channels can even be found in search, and shared and will show link previews.

The difference is in access control mechanism which automatically allows access only if one is a Member. Membership to the network is always free.

So all members can access and post into restricted channels.
