IRC/EFNet

EFNet (Eris Free Network), IRC Network created in August 1990, by Wikipedia contributor GregLindahl. EFNet is named as it is because it threw out the server eris.berkely.edu, which allowed anyone to connect servers, leading to security problems. The resulting argument split the IRC community of admins, but almost all admins (and users) ended up joining EFNet.
