YSTV IRC
From YSTV Documentation Wiki
YSTV maintains an IRC channel on Freenode, #ystv. The XChat client is recommended, though you are free to use any you wish. A web client is available at webchat.freenode.net.
NickServ
It is recommended you register your chosen nickname with NickServ in order to prevent impersonation. Type /msg nickserv register <password> <email address>
to register your name. You'll receive a confirmation email with a code. Once you're registered, upon entering any channel on the same network you can type /msg nickserv identify <password>
to confirm your identity and boot off anyone using your name.
