Can two computers share a conversation - other than the original two?
I created a conversation, then emailed the link to two other people. I was able to have one of them join me, but later after we disconnected. The other two computers tried connecting to that conversation and got "There are already two people in this conversation" (even though they all left earlier). Are the url links only good for one use?

Currently Hello only handles 2 users, one of which has to be the user who started the conversation. Expanding to handling more users is in the works, but I don't know the release date for that. And I don't know if the originator can not be involved - like no hand-offs allowed in the future either.
Overall, my slim understanding of WebRTC is that it is peer-to-peer and can't be "handed off" to another participant. IOW, if the originator signs off the conversation ends.
In your situation, when you ended your participation you may have lost or closed the window, but your connection might not have been terminated - thus the message about "There are already two people in this conversation". If you had closed Firefox or shut off your device, the conversation would have been terminated - hence my suspicion that "you" were still connected.
