tilix hosts an XMPP server! To connect, open your ~/XMPP_CREDENTIALS file to obtain your username and password. All users on the system are automatically registered and you do not have to request this file. In your clients, specify tilix.art as the server or use your username like user@tilix.art. Accounts are only granted to tilix.art users and cannot be registered manually. If you are an existing user on the system, you may use any XMPP client outside of your tilix session to connect at any time from anywhere.
