To view your web panel, copy and paste the URL of your server (such as example.ircnow.org) into your web browser.

To add a new network, type:

/msg *status addnetwork newnet
/msg *status jumpnetwork newnet
/msg *status addserver irc.example.com +6697
/msg *status connect

Replace newnet with your net name and irc.example.com with the correct server. If you are using port 6667 (plaintext), then replace +6697 with 6667.
