IRC is the main way to contact admins and developers when you need report someone for behavior on a server, to confirm an event, or other such reasons.

We use the #nordinvasion channel on the Rizon network.

You can connect to IRC via webchat in your browser.

For a more stable connection with fewer time-outs, a stand-alone client can be used.

A few good ones are mIRC, KVIrc, and Quassel.

The server address is irc.rizon.net
For a standard connection, use ports 6660-6670 or 7000.
For a secure (SSL) connection, use ports 6697 or 9999.

See the Rizon Wiki for up-to-date server information.
