Foonetic is an IRC network. More information about it may be found on its website. If you need help on the network, please consult the FAQ and ask in #help.
Foonetic has services for registering nicknames and channels, amongst others. We are running Atheme irc services.
You can use Nickserv for registering nicknames so that other people won't take them, and ChanServ for maintaining control of channels.
Make sure to also take a look at Channel Modes & Bans for more info on channel modes and securing your channel.
