Many IRC servers, especially new ones, are not part of a network, this category is for "stand alone" servers. "Stand alone" servers can be very friendly, with almost a family feel to them. All stand-alone servers are not considered a network because they have services linked to them. They often have a much more specific reason for existing rather then "general" chatting which IRC networks have although it is not unheard of.
Please only submit servers that are stand-alone. They don''t have any other servers linked to them but might have services. IRC networks (two or more servers linked together) should be submitted to Computers: Internet: Chat: IRC: Networks.
