One of the largest IRC networks still in existence with a laid back administration that provides minimal services but doesn't overwhelm the users with hundreds of *Serv
bots. The primary service is X, the channel
bot, who provides many options for managers and
ops alike.
Undernet is very involved with its users, and holds frequent classes and interesting discussions or interviews in the #class channel. Channels are very
hard to register, and therefore if a channel is registered, then it is garunteed to be lively. It has frequent netsplits, but not quite to the caliber of EFnet and DALnet, making it a much more solid network. In general, the
help channels on Undernet are often nicer and more
humble than EFnet, but still
don't be surprised if you get banned for an arbitrary reason. There's always room for improvement.
