First of all, I want to say that you are doing a great job. IMO kontalk seems to be the xmpp messenger with the best user experience. And sorry for my english. Like we say in germany, it is not the yellow from the egg.
So I am hosting an ejabberd server on my raspberry pi for me and my friends and we are currently using conversations. Its not that bad but it seems to be hard for my friends to use a jabber-ID instead of a phone number and they are currently forgetting their passwords, so they always find it too complicated.
When I migrate to the kontalk-Server (I guess tigase?), can I use the docker-image on my ARM powered pi?
And when my friends are using this server and not the official kontalk server, can they find users from other servers and can they be found by external users? How is this exactly working?
Do I have to open the server for registrations? I am asking this because my raspberry pi would be overwhelmed with more users.
And one question about the client: Is it possible to add someone by JID from the kontalk client or will this be possible in the future? Some friends from other servers will still use conversations or gajim and I need to chat with them.
Thank you for the help and for the great job you are doing
