         <p>Rooms are an publicly accessible Scuttlebutt peer, but unlike <a href="#pubs">pubs</a> they don't host feed data from other peers. The main feature rooms provide is a way for peers to find each other and establish tunnelled connections among themselves as if they were on the same network. They also provide more moderation tools than a pub with multiple user-levels and different privacy modes.</p>

         <p>Rooms differ from pubs because even though they're a Scuttlebutt peer, they are not meant to aid replication by <i>diminishing the number of hops between peers</i>. Instead, they provide a simple way for peers to find and connect to each other even though these peers might not have publicly accessible connections, and thus no <i>follow</i> messages are used in the rooms workflow.</p>
