Adult message boards and irq chat servers
DALnet ircd modifications were made by Alexei "Lefler" Kosut.DALnet was thus based on the Undernet ircd server, although the DALnet pioneers were EFnet abandoners.IRC clients are computer programs that users can install on their system or web based applications running either locally in the browser or on a 3rd party server.These clients communicate with chat servers to transfer messages to other clients.They had obtained the program from one of Jarkko's friends, Vijay Subramaniam—the first non-Finnish person to use IRC.IRC then grew larger and got used on the entire Finnish national network—Funet—and then connected to Nordunet, the Scandinavian branch of the Internet.
At this time Jarkko realized that the rest of the BBS features probably wouldn't fit in his program.
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.
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".
