For the latter purpose, the Undernet implemented timestamps, new routing and offered the CService—a program that allowed users to register channels and then attempted to protect them from troublemakers.
Another fork effort, the first that really made a big and lasting difference, was initiated by 'Wildthang' in the U. October 1992 (it forked off the EFnet ircd version 2.8.10).
It was meant to be just a test network to develop bots on but it quickly grew to a network "for friends and their friends".
As Greg "wumpus" Lindahl explains: "it had a wildcard server line, so people were hooking up servers and nick-colliding everyone".
The "Eris Free Network", EFnet, made the eris machine the first to be Q-lined (Q for quarantine) from IRC.
History showed most servers and users went with EFnet.
