The largest nets are EFnet , Undernet , IRCnet, and DALnet . On IRC, people know you by a nickname. At the present time, you will always have the same name as your username. However, on WebTV, you can create up to five secondary users and use any of them to chat on the Internet. Group conversations occur on the thousands of channels on each network.
Channels can be open to everyone or only to friends.
Channels are dynamic because anyone can create a new channel, and a channel disappears when the last person on it leaves. By default WebTV users can chat on Talk City , one of the largest web-based chat servers. If you still want to chat on Talk City, you must go to their home page or WebTV page . Many people have abandoned Talk City for a real IRC network after this debacle. Indeed, Talk City is like the tip of the iceberg when it comes to chatting.
