Assuming you've connected to the server, you'll have to register your nickname with nickserv to join #sythe
To do so, type:
/NS REGISTER <a password> <
[email protected] (MUST BE REAL)>
IE: /NS REGISTER mypassword
[email protected]
you'll receive a confirmation email which will contain a confirmation code that you'll have to use to complete the process. oh, and make sure that if you don't see it in your inbox to check your spam folder, it'll probably be in there. The code, as well as instructions on how to use it, are inside this email.
After that, you'll have to 'identify' as the owner of that nickname every time you connect to the IRC. (as in, if you disconnect for whatever reason you'll have to do this when you reconnect)
Type /NS IDENTIFY <the password>
IE: /NS IDENTIFY mypassword
Note: passwords are case-sensetive
then you are free to join #sythe and chat with everyone
