I don&#x27;t actually have any idea about how group chats are implemented in Tox, but I don&#x27;t see why you can&#x27;t send messages to the people in the group to redistribute when people get back. It sounds like it might have history consistency issues, but maybe they already do that.<p>I assumed you were talking about one-on-one message relaying, which is probably what most people would care about. That can&#x27;t really be solved, since one of the goals of Tox is also to prevent 3rd parties from being able to tell who you are talking to. Can&#x27;t do that if you have to broadcast to users &quot;send this message to &lt;x&gt; when they get back&quot;...
