People may make their own clients later and or share them, but for now the most simple way to send a message is with the `telnet` command in your terminal. Let's send a message to me: telnet 104.193.225.130 6672 [Type your message here] CTRL-] That last line ends the message. The practices of how to send a message may change in the future as well as what to expect back from a person or program, as practices change over time. But one thing is for certain, as practices change they will be a product of what practices the community chooses to adopt rather than any top-down standard. One very good practice is saying who you are and leaving contact info for someone to contact you back.
